Figuring out why the check engine light won't go off in a vehicle can be a complicated task. There are numerous things that can go wrong with an engine and lead to the light coming on. In some cases, the engine is simply old and no longer functional enough for a vehicle. It is a good idea to get an old engine replaced before it goes out altogether and leaves you without a working vehicle to drive. Take a look at this article to learn more about an engine so you can get a general idea of what might be causing the check engine light to stay on.
Engine Parts Might Be in Bad Shape
Damaged engine parts might be responsible for the check engine light staying on. One of the ways for the engine parts to get damaged is from rust accumulating on them. Rust is a problem because it can prevent the parts from moving as freely as they should. Another thing that causes damage to engine parts is when they rub together. The rubbing causes the parts to shed metal pieces, and it can also lead to a large amount of friction that causes the parts to continuously get hot.
The Engine Must Have a Sufficient Amount of Oil
A lack of oil can lead to the check engine light coming on. Oil is actually one of the most important things that your engine must have to function properly. For example, without a sufficient amount of oil, the piston might not move as it should to allow the engine to obtain air and gas from the cylinder. Low engine oil also leads to parts such as the rods not being lubricated enough, so they begin rubbing against other parts. Visit a dealer to obtain oil for your vehicle if you believe your vehicle is low on it.
There Isn't Enough Coolant in the Vehicle
A low level of coolant has a bad effect on the engine, as it can lead to it overheating. Get the coolant levels checked, as you might need to get more placed in your vehicle so the engine light will go off. It is also possible that the coolant lines are the root of the problem. For example, the lines might be leaking the coolant out before a sufficient amount of it makes it to the engine. Damaged coolant lines can easily be repaired or replaced by a mechanic like those at http://www.smallandsonsoil.com.
