Why does the check engine light in my Avalanche 2500 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 Avalanche 2500 firing up its circuits. The light should turn off in a bit, but come see us if it doesn't.

Why does my Chevrolet engine sound different?

Unusual noises can signal a problem with your Chevrolet Avalanche 2500 engine. Tapping or knocking could mean you need an oil change. A high-pitched whistle could signal an intake leak or misaligned belt. Squealing may be caused by a loose fan belt, and grinding might be coming from the brakes, not the engine.

What could damage my Chevrolet Avalanche 2500 engine?

Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, revving the engine while still in Park, or accelerating too quickly, too soon. Steer clear of these habits to help protect engine performance and efficiency.

Can I add water to my Chevrolet Avalanche 2500 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.

Why did my Avalanche 2500 engine suddenly stop?

Reasons your Avalanche 2500 car engine may suddenly stop include engine overheating, electrical troubles, mechanical issues, ignition system problems, faulty sensors, and low fuel.
