Why does the check engine light in my S15 Jimmy turn on when I start my car?

Generally, your check engine light turning on upon ignition is not a bad thing. It’s just your S15 Jimmy firing up its circuits. The light should turn off in a bit, but come see us if it doesn't.

Why is my GMC S15 Jimmy making engine noise?

Strange engine sounds can be a sign something’s off in your GMC S15 Jimmy. Knocking or tapping could be a symptom of low oil. Whistling sounds could mean you have an intake leak or misaligned belt. Squealing can be traced back to a loose fan belt, and grinding might be a sign of brake problems rather than engine issues.

What could damage my GMC S15 Jimmy engine?

Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, flooring the gas pedal while the car is in Park, or slamming the gas pedal while the engine is still cold. Steer clear of these habits to help protect engine performance and efficiency.

Can I use water in my GMC S15 Jimmy radiator?

Only in emergencies. A 50/50 mix of coolant and water (or a pre-mixed) coolant is recommended. However, if you must keep driving when you're out of coolant, it's better to drive with water in your coolant reservoir than nothing.

What can cause the engine in my S15 Jimmy to suddenly stop?

Your S15 Jimmy car engine could stop suddenly due to low fuel, electrical issues, overheating, a faulty ignition system, mechanical troubles, or sensor problems.
