Signs your engine needs attention
- The check engine light is on or flashing.
- Rough idle, stalling or hesitation when you accelerate.
- Knocking, ticking or tapping sounds.
- The temperature gauge climbs or an overheating warning appears.
- Poor fuel economy or noticeable loss of power.
- Smoke from the exhaust, or oil or coolant leaks under the vehicle.
How engine problems are diagnosed
Diagnosis comes first. A check-engine light is a code, not a diagnosis — the right repair depends on what is actually causing it. Typical engine work ranges from replacing sensors, spark plugs, belts and hoses to repairing leaks and cooling-system parts to larger repairs.
We like to show customers the parts that were changed and explain why, so you can make an informed decision. Regular oil changes are one of the simplest ways to protect your engine, and a failing exhaust or electrical system can also trigger engine warning lights.
Common questions about engine repair
What does the check engine light mean?
It means the vehicle’s computer has detected a problem with the engine, emissions or related systems. The cause can be minor, like a loose gas cap, or more serious, so it should be checked.
Is it safe to drive with the check engine light on?
A steady light usually means you can drive carefully to get it checked. A flashing light often signals a misfire that can damage the catalytic converter; reduce your driving and get the vehicle checked promptly.
My engine is overheating. What should I do?
Pull over safely and turn the engine off. Let it cool before opening the hood and never open a hot radiator cap. Then call for help rather than driving on, since overheating can cause major damage.
