Why does the check engine light come on when I start my Sunfire?

It's okay if your check engine light comes on when you first start your vehicle. This is just your Sunfire testing its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.

Why is my Pontiac Sunfire making engine noise?

Strange engine sounds can be a sign something’s off in your Pontiac Sunfire. Tapping or knocking could mean you're low on oil. Whistling could mean a belt is misaligned or there's an intake leak. 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 Pontiac Sunfire engine?

Certain driving habits can hurt your engine. These habits include driving on an empty fuel tank, revving the engine while still in Park, or pushing 'the pedal to the metal' before the engine has warmed up. Help sustain your engine’s performance and efficiency by staying miles away from these bad driving practices.

Can I use water in my Pontiac Sunfire radiator?

An emergency is the only time you should consider putting water in your radiator. Outside of that, it’s recommended you use a pre-mixed coolant or a 50/50 blend of water and coolant. However, if you need to continue driving your Sunfire when you’re out of coolant, having water in the coolant reservoir is better than nothing.

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

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