ENGINE MAINTENANCE

Engine maintenance is vital to keep your car or truck operating at peak performance. It also impacts the longevity of your vehicle's engine. Trust the experts at Kar Tech to help you protect your investment. Call us at 636-441-8121 or visit our shop in Saint Charles 63304.

These are some of the engine maintenance services we offer.

Fuel Injection
Fuel injection is a system for admitting fuel into an engine. Since 1990, fuel injectors have completely replaced carburetors as the primary means of getting gasoline into the engine. A fuel injector atomizes the fuel by forcibly pumping it through a small nozzle (under high pressure). Failure of the fuel injection system means poor performance and ultimately destroys the engine. Make sure your vehicle's fuel injection system is maintained properly. For all your fuel injection maintenance and replacement needs, call 636-441-8121 or visit Kar Tech today.

Ignition
An ignition system is a system for igniting (using an electric spark) a mixture of fuel and air in a gasoline engine. A properly working ignition system means a properly starting engine and high performance from your car. For all your ignition system maintenance and replacement needs, call or visit Kar Tech today.

Ignition Wires & Cables
Ignition cables also known as spark plug wires are an important part of your car's ignition system. They transfer the spark from the ignition coil to spark plugs that ignite the mixture of fuel and air. The mixture starts the engine. Over time, ignition wires and cables get weak and break down. This makes it impossible for the spark to reach the engine cylinders. This results in the engine misfiring. The car will eventually fail to start. If it does start, it will run poorly. Common symptoms of faulty ignition cables and wires are: poor gas mileage, engine misfires, engine light is on, and engine may vibrate. If your car needs new ignition cables and wires, call or visit Kar Tech in Saint Charles, MO 63304. Here, you will have the wires and cables changed by a top-rated mechanic.

Spark Plugs
A spark plug delivers electric current to the combustion chamber from the ignition system. Spark plugs that haven't been changed for a long time can cause ignition problems. At Kar Tech, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 636-441-8121 or visit Kar Tech today.



Spark Plug Questions and Answers

Q: How do you know when a spark plug needs to be replaced?
A: The most common sign a spark plug needs replacing is the feeling that the car's engine is hesitating when accelerating, but other signs may include misfiring at start up, rough idling, sluggish acceleration, declining fuel economy and engine knocking.

Q: What else should I replace when replacing spark plugs?
A: If you are considering having your vehicle's spark plugs replaced, there's a high probability that your spark plug wires need changing as well. Ignition wires become brittle over time. Old ignition wires can break and cause misfires or declining fuel economy.

Serpentine Belt Question and Answer

Q: How do I know if I need to replace my car's serpentine belt?
A: If your serpentine belt is failing, you may notice performance issues with your vehicle. The vehicle may frequently overheat. Your air conditioning or power steering may fail to work or not work properly. You may notice your vehicle battery failing to recharge if the alternator is affected by a bad serpentine belt. If you start to notice any of these issues we encourage you to bring your vehicle to Kar Tech as soon as possible to avoid bigger problems and breakdown.

Check Engine Light Questions and Answers

Q: What could cause a check engine light to come on?
A: Come by Kar Tech and we can diagnose the reasons for a check engine light turning on. It can range from something serious like a faulty catalytic converter or potential engine failure to something simple like a loose gas cap or the need for a simple 50K or 100K mile manufacturer maintenance check.

Q: Is it okay to drive with the engine light on?
A: The short answer, "No." The longer explanation is the light may indicate a serious engine failure and continuing to use your car as if nothing is wrong could result in a very expensive repair bill. The check engine light means you should stop driving and have your car looked at as soon as possible by a professional at Kar Tech in Saint Charles.

Q: What is the most common problem with my check engine light?
A: A loose gas cap is the most common cause of a check engine light coming on. But the best method to determine why the check engine light is on is to have a professional at Kar Tech read the diagnostic code in the car's internal OBD computer.

Q: What does a solid check engine light mean?
A: A steady check engine light indicates a non-emergency issue. Come by Kar Tech and we can help.

Q: What does an intermittent flashing check engine light mean?
A: Flashing check engine lights warn of severe situations requiring immediate attention. Get your vehicle to an auto repair shop as quickly as possible or get it safely parked and call a tow truck to take it to your preferred auto repair shop.

Q: Can I turn off my check engine light myself?
A: It is a very bad idea to try to resolve a check engine light yourself. The DIY method to turn off a check engine light without a scanner is disconnect the battery cables, wait 1 minute, and reconnect the battery cables. If the underlying issue has been resolved, the light should go off. But modern automobiles rely on battery power to maintain important systems such as the O2 sensor and ADAS systems. By disconnecting the battery, you run the risk of damaging these delicate and expensive to replace computer-driven components. If your check engine light is on come by Kar Tech in Saint Charles. Turning off a check engine light is often inexpensive and simple.
