Posted on October 28, 2022 by Autohaus

Temperatures are dropping, and rising, and dropping again. Quite typical for Indiana climate patterns this time of year. One of the most effected automotive parts during this seasonal transition are tires. And as fall continues and the winter months approach, many drivers begin to worry about how the cold weather will have an effect on their cars. One of the most common questions is, “What happens to my car tires in the cold?”

Continue below to learn exactly what you need to know about the way cold temperatures affect your car tires, plus a guide on how to check your tire pressure.

Top 5 Ways Cold Weather Affects Car Tires

❶ Cold weather can cause your tires to lose pressure.

As the temperature drops, so does the air pressure in your tires. This can lead to a decrease in performance and fuel efficiency, as well as increased wear and tear on your tires. It’s important to check your tire pressure regularly during the winter months to ensure that it stays at the proper level.

❷ Cold weather can make your tires harder.

The cold weather can make your car tires harder, which can lead to less traction and increased wear. It’s important to check your tires regularly for signs of wear and tear, and to have them replaced when necessary.

❸ Cold weather can reduce the lifespan of your tires.

The cold weather can reduce the lifespan of your tires by causing them to crack and degrade faster. It’s important to inspect your tires regularly for signs of damage, and to have them replaced when necessary.

❹ Cold weather can make it more difficult to change a tire.

If you have a flat tire, the cold weather can make it more difficult to change. It’s important to be prepared for this possibility by having the proper tools and knowledge to change a tire in the cold.

❺ Cold weather can increase the risk of a blowout.

The cold weather can also increase the risk of a tire blowout. This is because the air pressure in your tires is lower in the cold, which makes it more likely for the tire to fail. It’s important to check your tire pressure regularly and to have your tires replaced when necessary.

Conclusion…If you’re concerned about how the cold weather will affect your car tires, be sure to follow these tips. By taking care of your tires, you can help to ensure that they last longer and perform better in the cold.

How to Check Tire Pressure

It is important to check your tire pressure regularly to ensure safe driving conditions and to extend the life of your tires. You can purchase a tire pressure gauge at most auto parts stores. To check your tire pressure, remove the valve cap from each tire and press the gauge firmly onto the valve stem. The gauge will give you a reading of the pressure in your tires. Compare this to the recommended tire pressure for your vehicle, which can be found in your owner’s manual or on a placard located on the driver’s side door jamb or glove box.

If your tires are underinflated, use a portable air compressor or visit a service station to inflate them to the proper pressure. If your tires are overinflated, release some of the air by pressing on the gauge and then removing it from the valve stem.

Check Your Tire Tread Too!

It is also a good idea to check your tire tread regularly. You can do this by inserting a penny into the tread groove with Lincoln’s head upside down. If you can see the top of Lincoln’s head, your tread depth is less than 2/32nds of an inch and it is time to replace your tires.

Conclusion…Checking your tire pressure and tread regularly will help ensure safe driving conditions and extend the life of your tires.

Most Common Signs of a Failing Car Radiator

Posted on October 10, 2022 by Autohaus

A car radiator is a type of heat exchanger. It is used to transfer heat from the hot coolant that flows through it, to the air flowing around it. The radiator is made up of a series of metal fins that are connected to each other. The coolant flows through the fins, and the air flowing around the radiator helps to transfer the heat away from the coolant. The radiator is usually located at the front of the car, where it can get good airflow. It is important to keep the radiator clean and unobstructed, so that it can work effectively.

If you suspect that your car radiator is having trouble, you are probably right being as though the signs are hard to miss. Continue below to review some of the most common signs of a failing car radiator, plus how to tell if you need radiator repair or replacement.

Car Radiator Repair Carmel Indiana 317-571-0800

How to Tell if Your Car is Having Radiator Problems

A car radiator is vital to the proper functioning of a vehicle’s engine and helps to keep it cool. Over time, however, radiators can develop problems that can lead to a breakdown. Here are some common signs of radiator problems:

▷ Leaks – One of the most common signs of radiator trouble is leaking coolant. Coolant leaks can be caused by a number of issues, including cracks, holes, or loose fittings.

▷ Overheating – Another sign that your radiator may be failing is if your vehicle’s engine begins to overheat frequently. If the radiator isn’t able to properly cool the engine, it will cause the engine to overheat.

▷ Corrosion – Another sign of radiator problems is corrosion. Corrosion can cause the radiator to leak or become clogged, preventing proper coolant flow.

▷ Strange Noises – If you hear strange noises coming from your vehicle’s engine, it could be a sign that the radiator is failing. These noises may include hissing, bubbling or gurgling sounds.

If you notice any of these signs, it’s important to have your car radiator checked by a professional Carmel IN mechanic as soon as possible. Radiator problems can quickly lead to engine damage, so it’s important to nip them in the bud before they cause too much harm.

Radiator Repair and Replacement Costs

The cost of car radiator repair will vary depending on the severity of the damage and the make and model of your vehicle. However, on average, you can expect to pay between $200 and $400 for the repair. If your car radiator is leaking, it is important to have it repaired as soon as possible to avoid further damage to your engine. However, if the damage is not severe, you may be able to repair it yourself with a radiator repair kit. These kits can be purchased at most auto parts stores and usually cost between $20 and $50.

If you have a car radiator that needs to be replaced, the cost will be significantly higher. On average, you can expect to pay between $800 and $1,200 for the replacement. The exact cost will depend on the make and model of your vehicle, as well as the labor costs associated with the replacement. However, if you have a high-end car, the cost could be even higher.

5 Car Maintenance Services That Protect Your Life

Posted on September 26, 2022 by Autohaus

When it comes to driving, whether yourself or your loved ones, safety is always front of mind. There is no better way to ensure optimal safety and performance of your vehicles than responsible auto service and maintenance. Not only should you have your vehicles inspected by a licensed mechanic, according to the automotive manufacturer factory scheduled maintenance recommendations, but you should also know how to visibly inspect and care for your car on your own.

Although all manufacturer recommended auto services and car care best practices should be followed, continue reading to learn the top five auto services that are the most critical to your overall safety.

Car Brake Auto Service Carmel Indiana 317-571-0800

5 Safety Focused Auto Services

To protect yourself from danger, out on the road, these five safety focused auto services should be at the top of your routine car maintenance priority list: brake replacement, shocks and struts replacement, exterior light inspections, windshield wiper fluid refills, and car fluid refills.

Car Brake Replacement

Car brakes are not designed to last forever. At some point in time, your vehicle’s car braking system will need either a full replacement or parts replacement. When car brakes wear down, they lose performance value. Since brakes are arguably the most important safety feature of the vehicle, a decline in corporate performance is a serious issue that requires immediate attention. As for parts, brake pads can deteriorate over time, so they need to be changed on a routine basis to ensure optimal braking and friction and performance.

Shocks and Struts Replacement

Shocks and struts generally began to experience wear and tear between 50,000 and 100,000 miles. This is typically a middle-aged vehicle, with struts in the front and shocks in the rear end. If you’re feeling like your car is bouncy when you drive or if it’s sagging on one end, you could have a damaged strut or blown shock. Damaged shocks and struts can pose serious risks out on the road since a car can become less responsive to steering and braking.

Exterior Light Inspections

It is important to routinely check on the exterior lights of your vehicle. This is something that you can do all on your own, or even enlist the kids to do for you. Simply insert your key into the ignition. Clicking it over one time so that your lights turn on. But your engine stays off. Then, while monitoring reflections around you or with the help of a partner, check to see that your turn signals, windshield Wiper, parking lights, headlights, brake lights, and brights are all working. If you ever drive in the evening hours or at night, exterior lights are vital to your overall safety on the road. Even if you are a daytime driver, inclement weather conditions and foggy weather can put you in serious danger. If your exterior lights are not functioning properly.

Windshield Wiper Fluid Refills

On the subject of inclement weather conditions, having a full reservoir of windshield wiper fluid is critical to your visibility, which is critical to your overall ability to operate your vehicle safely. Not only is it important to use a quality windshield wiper fluid, but it is also important to routinely fill it up, especially during times of frequent use. Along with windshield wiper fluid, it is important to replace your actual windshield wipers every year or two. And unlike many other products in life, price does matter. The more expensive the windshield wipers are, the better performance you can expect.

Automotive Fluid Refills

Along with windshield wiper fluid, your vehicle requires six other vital automotive fluids that need to be refilled on a routine basis. These fluids include motor oil, coolant (radiator fluid/antifreeze), brake fluid, power steering fluid, transmission fluid, differential fluid (if applicable), and battery fluid (if applicable). Refer to your owner’s manual for instructions on how to check and refill these fluids for your make and model vehicle.

Recommended Roadside Safety Kit for Volkswagen Drivers

Posted on August 17, 2022 by Autohaus

Roadside emergencies do happen. So, it is important that you be adequately prepared for both the anticipated and the unexpected, whether driving around town or across state lines. As a Volkswagen driver, the need for security runs deep, as you chose VW automakers because they are known to deliver optimal safety, dependability, and performance. A comprehensive roadside emergency kit can help you achieve an even higher level of assurance while driving your trusted Tiguan or beloved Jetta.

Continue reading to review some of the top recommended items to put into your own Volkswagen roadside emergency kit.

Volkswagen Auto Service Carmel Indiana 317-571-0800

Items to Put in a Volkswagen Roadside Emergency Kit

You can purchase all recommended roadside emergency kit items at any local department store with an automotive section, or through an online retailer. Your total out-of-pocket cost for your VW roadside emergency safety kit will depend on the brands you choose and the scope of function for each item. You can expect to pay anywhere from $25 to $200.

Spare Tire

Depending on your trunk space availability, you may or may not be able to add a spare tire into your roadside emergency kit. Instead of a spare, you can choose alternatives like a donut tire, run-flat tires, fix-a-flat products, or even tire patch kits.

First Aid Kit

A first aid kit is a must when it comes to roadside safety. You can make your own custom kit or purchase a prepackaged one. Prepackaged roadside kits come in a wide variety of sizes and selections. Choose one that at least has the basics, like bandages, alcohol pads, gauze, adhesive tape, aspirin, antiseptic wipes, hand sanitizer, and antibiotic ointment. Larger packs might have items like thermometers, blankets, scissors, tweezers, nail clippers, aloe lotion, hand warmers, and more.

Multi-Use Tool

A multi-use tool might also be included in your first-aid kit. It is a multi-functional tool that can be used as a pair of scissors, knife, pliers, wire cutters, and sometimes a wrench and screwdriver. You can purchase this type of product at any local department store with a home improvement section, online retailer, or hardware store.

Road Triangles or Flares

You can choose between roadside flares or reflective triangles. These are used to mark your vehicle’s boundary and protect your spot from roadside collisions. These are especially important during high traffic times, on highways, in inclement weather, and at night.

Phone Charger

Always have a spare phone charger in your car. Take a step further and have a portable phone charger battery in your Volkswagen in case you don’t have an outlet for your charger or the outlet in your car does not work.

Jumper Cables

Jumper cables are not an essential item, but they do come in handy when a car battery dies. Jumper cables are more compact in design these days, so they do not take up as much room as conventional or older model jumper cables.

Water

Have extra bottles of water in your Volkswagen to prevent dehydration. Water has other applications when it comes to roadside emergencies too, like cleaning wounds, side mirrors, or windshields. Keeping water in your car is especially important in the summer season when temperatures are higher.

Blanket

You can go as far as having a designated car blanket. When you are stuck on the side of the road, whether managing your roadside emergency or waiting for assistance to arrive, you might need a blanket to keep warm, especially if it’s the dead of winter and your heat won’t work!

Routine maintenance is the best way to keep your Volkswagen safe on the road. Not sure where to take your luxury German vehicle?

How to Calculate Your Car’s Gas Mileage

Posted on August 4, 2022 by Autohaus

Gas prices will always be at the forefront of our budgets. Fuel costs seem to increase with every turn of the market, regardless of direction. For the sake of your financial goals and money-saving priorities, try calculating your vehicle’s gas mileage to see if you are getting the most out of every gallon. Continue below to learn how you determine your car’s MPG, plus what you can do to improve fuel efficiency from there.

Car Maintenance Mechanic Carmel Indiana 317-577-0800

Gas Mileage 101

The number of miles your car can drive on one gallon of gas is referred to as gas mileage, or miles per gallon (MPG). This is also known as fuel economy. The more miles per gallon your car gets, the more fuel efficient it is.

To achieve the highest level of fuel economy possible for your vehicle, the key is regular maintenance and quality automotive parts and products. The better you care for your car, the better it will perform and the longer it will last.

To understand your vehicle’s routing car maintenance needs, refer to the owners’ manual. If you do not have the owners’ manual, you can download one online for your make and model vehicle, or you can ask a trusted Carmel IN mechanic for a recommended auto maintenance schedule.

Calculating Your Vehicle’s MPG

There are 7 simple steps to calculating your vehicle’s miles per gallon. It will take some time, as well as some basic, elementary-level math. Here’s how to determine a car’s MPG:

➊ Fill Your Tank All the Way – Be sure your gas tank is topped off all the way.

➋ Record the Odometer Reading – Write down the number of miles that reads on your odometer. You may also set your odometer’s trip meter is applicable.

➌ Use Up All Your Gas – Drive your vehicle as you normally would until the gas tank is on E again. This should take a week or so depending on how much and how far you drive on a daily basis.

➍ Record the Odometer Reading AGAIN – Write down the number of miles that shows on your odometer.

➎ Record the Number of Gallons Refueled – Write down how many gallons of gas it took to refuel your tank all the way full.

➏ Do the Math – Subtract the first odometer reading from the second reading. This will tell you how many miles your car drove on one tank of gas.

➐ Do Some More Math – To get your MPG, divide the number of miles you drove by the number of gallons it took to refill your gas tank.

Does Your Car Have Good Fuel Economy?

The U.S. Environmental Protection Agency provides us with a fuel economy rating system that evaluates vehicles on a scale from 1 to 10, with lower numbers being worse and higher numbers being better. If your vehicle has an MPG less than 14, you are assigned a rating of 1, while a MPG of 44 or more rates a full 10.

Continue below to learn five budget-friendly ways to extend the life of your import or luxury car.

Import Car Mechanic Carmel Indiana 317-571-0800

Cost-Effective Car Maintenance for Luxury Vehicles

It is in everyone’s best interest to keep their vehicles in good working condition for as long as possible. Not only is car maintenance important for the safety, efficiency, and performance of your vehicle, but it is also important for resale or trade-in value. Fortunately, implementing cost-effective car maintenance for a luxury vehicle is a viable endeavor. You just have to know what your car needs and how to get it done.

How to Ensure Your Vehicle Lasts as Long as Possible

Here are the top recommended car maintenance tips to make your luxury or import vehicle last longer than any other car you’ve ever owned:

Follow the Manufacturer’s Service Schedule

In your owner’s manual, you will find a very detailed service schedule for your particular make and model vehicle. By adhering to this manufacturer’s service schedule, you automatically extend the life of your luxury or import vehicle.

Check Your Automotive Fluids Regularly

Every vehicle requires seven essential automotive fluids, including motor oil, brake fluid, transmission fluid, radiator fluid (coolant/anti-freeze), battery fluid, power steering fluid, and windshield wiper fluid. Some cars might even require additional automotive fluids, such as differential fluid. To support a long-lasting life for your vehicle, it is important to regularly check that these automotive fluids are at their proper levels.

Do Not Skip Oil Changes

As just mentioned, automotive fluids are very important to all vehicles. This is especially true when it comes to motor oil, being as though it lubricates the internal moving parts within the engine that create heat and friction. For this reason, oil changes are vital. Many people think they can hold off a little longer or skip out altogether on a routine oil change, but this is a very bad idea. If you want your car to last a very long time, have the oil changed out regularly.

Do Not Ignore Odd Sounds or Vibrations

As the primary driver of your import vehicle, you know it’s performance patterns pretty well. If you begin to notice strange sounds or vibrations happening in idle or while driving, it is important to have them checked out immediately by a Carmel Indiana luxury car mechanic. If this sounds or vibrations are fairly new, it is probably a minor problem. But it is important to get this minor problem resolved before it turns into a major one.

Pay Close Attention to Your Tires

Your car tires are one of the most vital components seeing as though they are the primary point of contact between your car and the ground, making tire care a vital element to any automotive maintenance plan. It is important to pay close attention to your tires, inspecting them periodically for proper inflation. Not only do you want to ensure that your tires have good air pressure, but you also want to look for signs of dry rot or flat spots. These damages can happen to cars that are not driven very often.

Continue reading for the ultimate quick-guide to jump starting a dead car battery!

Auto Electrical Repair Carmel Indiana 317-571-0800

Emergency roadside assistance kits typically contain items such as jumper cables, road cones, flares, jacks, blankets, cell phones, and more, and can be purchased almost anywhere. It is highly recommended to purchase and carry one of these emergency kits for yourself or your teenage driver. They come in a small, convenient case that can easily fit in the trunk or backseat of any vehicle. Once you have the items you need to jump start a dead car battery, you can rest comfortably knowing you’re prepared. Next, you simply need to review the instructions on how to jump start a battery.

Car Battery Life

Car batteries typically last anywhere from three to five years, depending on the make and model vehicle, the age of the vehicle, and the condition it was kept in. It may also depend in the number of miles driven, overtime. Car batteries run on battery fluid, and this fluid eventually runs out, causing the battery to die. There are other reasons why a car battery can die, too.

Exposure to extreme temperatures can cause a car battery to die, as well as, leaving the lights on for an extended period of time when the car is not in use. Other instances when a car battery might not be functional is when a vehicle has not been driven in a long time. No matter which reason causes your car battery to die, some cases will call for a battery replacement altogether, while others will simply require a quick jump start.

Jump Start Guide:

Position the operational vehicle’s engine close to the dead vehicle’s engine so jumper cables can reach both.

Turn both vehicles off and remove keys from ignition.

Locate the car batteries for each vehicle.

Attach the negative and positive jumper cable clamp to the matching negative and positive sides of each battery (refer to owner’s manual to identify these areas).

Place the red positive clamps on the positive side of each vehicle’s battery and place the black negative clamps on the negative sides of each vehicle’s battery.

Be sure the clamps are secured, and the cables are not touching the engines.

Return the keys to the operational vehicle’s ignition and turn the engine on.

Allow the operational vehicle to run for 5 or 6 minutes.

With the jumper cables still secured, return the keys to the charging vehicle, and turn the engine on; the engine should turn on if the battery is charged enough.

If the engine does not turn over, keep the jumper cables in place and allow the battery to charge for another 5 minutes.

If the engine turns on, still allow the cables to charge the battery a few minutes longer.

If the engine does not start after charging the battery for more than 10 minutes, call a mechanic.

Before removing the jumper cables, turn both engines off (failure to do so will result in serious or fatal electrocutions).

Close the hood because now your battery is charged again!

Frequently Asked Questions About Tire Care

Posted on June 10, 2022 by Autohaus

As the sole point of contact between the road and your vehicle, car tires are arguably one of the most vital automotive systems. Good car owners take good care of their vehicle’s tires, staying current on all tire inspections, measurements, rotations, balances, and replacements. If you are new to the world of automotive maintenance, educate yourself on the importance of routine tire care.

Get started on the right path by reviewing some frequently asked questions about tire care, below.

Import Car Maintenance Carmel Indiana 317-571-0800

FAQ About Tire Maintenance

What Does Tire Care Involve?

Taking good care of your tires involves several routine maintenance responsibilities. Not only should you regularly inspect your tire tread and tire pressure, but you should also have your tires periodically rotated and balanced, especially if you regularly drive off-road or on rough or bumpy terrain.

Additionally, you want to ensure that the tires are compatible with your make and model vehicle. If you have the incorrect size tires, it can have a negative impact on fuel economy, safety, and automotive performance. If you have the wrong type of tires on your vehicle, it can have all sorts of incompatible effects, plus pose safety risks. Refer to your vehicle’s owners’ manual for tire recommendations.

What is the Proper Tire Tread Depth?

Brand-new tires generally have a tread depth of 10/32 or 11/32 of an inch (about a third of an inch). According to the U.S. Department of Transportation, drivers should replace car tires when the tread depth has receded below 2/32 of an inch. If the tire tread variance between your car tires is greater than 2/32 of an inch, you should have them rotated to even out the tread wear.

How Do I Measure My Tire Tread?

To measure where your tire tread depth is at, all you need is a penny. That’s right; a copper penny! Turn the penny upside down with Lincoln’s head facing out so you can see him. Then stick the penny inside a tire groove. If you can see Lincoln’s entire face, your tire tread depth is below 2/32 of an inch.

What is the Proper Tire Pressure?

Tire pressure plays an important role in your vehicle’s overall safety and performance. Tire pressure is measured in “pounds per square inch” or PSI. Car tires can lose up to 2 PSI of pressure every month. Colder temperatures tend to lower tire pressure, causing under inflation, while higher temperatures tend to cause overinflated tires.

Both underinflated and overinflated tires are unsafe. For this reason, it is important to routinely inspect your tire pressure, including your spare tire. Proper tire pressure varies depending on several factors. It is recommended to use an online tire pressure monitor tool to learn the recommended tire pressure for your vehicle. You may also refer to the manufacturer’s recommendation.

How Do I Measure Tire Pressure?

To measure tire pressure, you will need to purchase a tire pressure gauge. They are inexpensive and readily available at any local auto parts store, department store, or home improvement store. They are also available on any relevant online retailer. This tool will come with manufacturer’s instructions that will teach you how to use it. It is very simple and only takes a couple of seconds to obtain a reading. You can also take your vehicle into the shop for routine tire maintenance, which will include tire tread and pressure measurements, which should include tire pressure and tread service.

Do I Need to Rotate and Balance My Car Tires?

Although you don’t have to, it is recommended to have your car tires rotated and balanced on a routine basis. This will help ensure that all four tires wear down evenly. Most drivers will have their car tires balanced and rotated every 5000 to 7000 miles.

Can Tires Impact Fuel Economy?

Yes, tires can impact fuel economy. Improperly inflated tires will use up more gas in your tank. With proper tire care, you can help maintain good fuel economy in your vehicle. Additionally, you can swap out your current tires for more fuel-efficient tires. These tires are designed to deliver higher tire rolling resistance, which is the force required to get the tires to start moving. Consumer Reports revealed that “The Department of Energy estimates that 4 to 11% of fuel consumption is due to tire rolling resistance.”

Why Does My Car Not Come With a Spare Tire?

If your car does not come with a spare tire, there could be a number of reasons why. Most likely, you purchased your car used and the previous owner did something with it. Or, you have a newer model vehicle. Automakers these days are foregoing the spare tire for all sorts of reasons, mostly for the sake of cost savings and space-saving design.

Do I Need a Spare Tire?

It is highly recommended tire, either at home or in the trunk of your vehicle. Some cars don’t have space for a spare tire, which is why they didn’t come with one of the first place. In this case, you might want to consider run-flat tires or a tire inflation kit. These will help you out in a roadside emergency situation.

Most often, this is due to structural damage of the fuel pump itself, but sometimes, the pump is just clogged. If the car will not turn over at all, fuel pump damage is the likely culprit. If the engine cranks but won’t turn over all the way, you may just be dealing with a clogged fuel pump.

Sputtering and Stalling

If your car is routinely sputtering or stalling while driving, it could be an indication of a failing fuel pump. In most cases, the fuel pump is working at a low pressure, so the engine is not getting the fuel it needs to generate combustion. If the car starts, drives away, but then stalls, it is usually because your fuel pump is not doing its job, and the engine cannot keep the car running.

Rear Bumper Whirring

Backseat noises like whirring or humming can point directly back to the fuel pump. These noises are naturally generated by the operation of the fuel pump, but we usually cannot hear them. When the fuel pump starts to malfunction, it is forced to work harder, which can make the noises get louder.

Engine Surging

Do the engine revolutions randomly surge and swell while you drive? This is a common sign of a faulty fuel pump. Opposite of fuel pump clogs and low pressure, engine surging is caused by a malfunction that sends too much fuel to the cylinders. This often causes the car to suddenly pick up speed and soon after, slow down.

Increased Fuel Consumption

Noticing changes in gas mileage, specifically reduced gas mileage, is a common indication of a fuel system problem. As for the fuel pump, it can be responsible for increased gas consumption when its internal parts and bearings deteriorate or break. Deterioration or damage can cause extra gasoline to be sent to the engine, which goes unused.
