Why does the check engine light in my Prizm 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 Prizm firing up its circuits. The light should go off shortly. Bring your vehicle in if it doesn't.

Why does my Geo engine sound different?

Strange under-the-hood noises can point to problems within your Geo Prizm engine. Knocking or tapping could be a symptom of low oil. Whistling could mean a belt is misaligned or there's an intake leak. Squealing can indicate a loose fan belt, and grinding might be a sign of brake problems rather than engine issues.

What could damage my Geo Prizm engine?

Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, revving your engine while the vehicle is 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 Geo Prizm 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 Prizm to suddenly stop?

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