Anyone who has ever had to pull over to the side of the road with a stalled engine knows that catching a failing engine before it dies completely is a good move. However, this is not always easy. A failing engine does not always behave in the same way.

Here are a few signs that your engine may be going bad, and it’s time to get a professional engine diagnosis.

Check engine light

This is the most obvious one: If your check engine light is on, it’s a good time to check your engine. While many different things can trigger this light, it’s important to have your car looked at as soon as possible if it comes on, especially if you notice any of the following signs as well:

Unusual noises

A strange noise coming from your engine is one of the most common signs of engine trouble. This may come as a knocking, grinding, or squealing sound, and may be caused by engine bearings wearing out, by a worn out fan belt or brake pads, or by other engine trouble. If you hear any sort of unusual noise coming from the front of your car, it is a good time to have it inspected by professionals.


If you are seeing smoke coming from anywhere other than the tailpipe of your car, it’s imperative that you get your car inspected as soon as possible, and stop driving it in the meantime. Blue, black or white smoke can all be signs of car trouble, such as oil leaking out of the engine, a clogged air filter, or more serious engine problems. If there is unusual smoke coming out of your car or into the cabin, pull over and get it looked at as soon as you can.

Irregular driving

Sometimes, you can just feel that your car is “driving different.” If acceleration feels different, your car is shaking when resting, or anything else feels out of the ordinary, this could be a sign of engine trouble. Trust your instincts and get your car checked out by professionals as soon as you can.

Dripping fluid

If there is a puddle of fluid under your car after it has been sitting for a while, it could be the sign of a serious engine leak. If not addressed immediately, these sorts of leaks can become more and more difficult and expensive to fix, so it’s a good idea to get the leak looked at immediately.
