Why does the check engine light in my SL1 turn on when I start my car?

It's okay if your check engine light comes on when you first start your vehicle. It’s just your SL1 firing up its circuits. The light should go off shortly. Bring your vehicle in if it doesn't.

Why is my Saturn SL1 making engine noise?

Unusual noises can signal a problem with your Saturn SL1 engine. Tapping or knocking could mean you need an oil change. 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 coming from the brakes, not the engine.

What could damage my Saturn SL1 engine?

Certain driving habits can hurt your engine. These habits include driving on an empty fuel tank, flooring the gas pedal while the car is in Park, or pushing 'the pedal to the metal' before the engine has warmed up. Steer clear of these habits to help protect engine performance and efficiency.

Can I use water in my Saturn SL1 radiator?

It’s not recommended you put water in your SL1 radiator unless it’s an emergency. Under normal circumstances, use a 50/50 mix of water and coolant or a pre-mixed coolant. But, if you need to keep driving while out of coolant, using water is better than driving with an empty coolant reservoir.

What can cause the engine in my SL1 to suddenly stop?

If your SL1 car engine suddenly stops, it could be due to overheating, low fuel, a faulty ignition system, sensor problems, electrical system trouble, or mechanical issues.
