Your car’s has a myriad of components and numerous interconnected systems. Regular engine services are the easiest way to prevent a problem, as a service enables us to check and replace components before they wear or become damaged. Your GMC dealer in Kerrville, TX, can fix any possible problem. We’d like to give you some examples of engine problems we can repair.
Engine Knocking
A strange knocking sound under the hood is always a sign of trouble. When your engine has the correct balance of fuel-to-air, and the spark plug ignites the mixture, it burns in a carefully regulated way. Part of the mixture ignites, which creates a shockwave that ignites another part of the mixture, and the process continues until all the mixture in the cylinder has been consumed.
The knocking sound is caused when the fuel-air mixture burns unevenly, and the shockwaves created as it burns happen irregularly. This sound is not only annoying, but it’s a warning that you will suffer to the cylinders and pistons if the problem isn’t fixed. Some causes of this problem are worn spark plugs, a build-up of carbon in the intake manifold, and low-octane fuel. We’ll examine your engine to find the cause of the problem and fix it.
Illuminated Warning Light
There are many different warning lights on your dash. When your engine starts, all the lights illuminate and then go dark. If the engine warning light stays on, there’s something wrong with your engine. The warning light doesn’t identify a specific problem, but it does mean that you need to contact us ASAP, so we can investigate.
We can identify the problem by connecting your car’s computer to our diagnostic system. If something goes wrong, engine sensors will inform your computer, and the computer logs the problem with an error code. Once we have the error code, our expert technicians will repair the cause of the problem. Once the problem is fixed, the engine light will go dark again.
Old Oil
We all know that an engine needs oil. Oil lubricates all of your engine’s components and helps to protect them against friction damage. Over time, engine oil accumulates dirt and minute debris, which reduces its speed. Slower moving oil can’t work as effectively as it should, and it can even cause blockages in your engine.
If the oil needs replacement, the oil can-shaped warning light on your dash will illuminate. This is a sign that the oil needs to be replaced. An oil change is a quick process that enables your engine to work more efficiently and prevents damage.
If your engine isn’t working as well as it should, call us right away at Crenwelge GMC Kerrville.
