Why does the check engine light come on when I start my G20?

Generally, your check engine light turning on upon ignition is not a bad thing. This is a sign that your vehicle is 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 Chevrolet G20 making engine noise?

Strange engine sounds can be a sign something’s off in your Chevrolet G20. Tapping or knocking could mean you're low on oil. A high-pitched whistle could signal an intake leak or misaligned belt. Squealing can indicate a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.

What could damage my Chevrolet G20 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. Protect your engine’s performance and efficiency by distancing yourself from these habits.

Can I use water in my Chevrolet G20 radiator?

While it’s not recommended, you can use water in your G20 radiator in emergencies. Normally, you should only use a 50/50 mix of coolant and water or a pre-mixed coolant. However, if you are completely out of coolant and must continue driving, it’s better to have water in your coolant reservoir than nothing.
