Not all auto repair issues are as obvious as a flat tire. Engine problems can be difficult to detect, let alone diagnose. The experts at Excel Service & Towing in Rochester, NY, have provided comprehensive auto service and roadside assistance for more than 20 years, and they recognize even subtle signs of a car that requires engine repairs.

To prevent engine issues from worsening, Excel Service & Towing suggests keeping an eye out for these major issues:

• Illuminated Engine Light: Although drivers dread seeing this indication of trouble, remember the engine light comes on at the first sign of a problem. It signals many things, including fuel quality issues, worn-out spark plugs, or problems with your car’s sensors. The problem even can be as simple as a loose gas cap. It's imperative to respond to an engine light, but your car probably will be OK even if you have to wait a few days to address it.

• Difficulty Starting: If you need several attempts to start your car, your battery probably is run down and needs to be replaced. If you manage to crank the engine but the car doesn’t start, a defective fuel pump could be the problem.

• Overheating: Like the engine light, your vehicle has a warning light that turns on when the engine temperature is too elevated. When this happens, it's important to stop the car and consult a mechanic about engine repair. When your car overheats, the problem could be a broken fan or loss of coolant.

If you spot any of these problems, make an appointment for engine repair as soon as possible.
