Why does the check engine light come on when I start my V3500?

It's okay if your check engine light comes on when you first start your vehicle. It’s just your V3500 firing up its circuits. The light should go off shortly. Bring your vehicle in if it doesn't.

Are GMC V3500 engine noises bad?

Strange under-the-hood noises can point to problems within your GMC V3500 engine. Tapping or knocking could mean you need an oil change. 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 GMC V3500 engine?

Certain driving habits can damage your engine and should be avoided. These habits include 'running on fumes,' 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 add water to my GMC V3500 radiator?

It’s not recommended you put water in your V3500 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 could cause my V3500 engine to suddenly stop?

Reasons your V3500 car engine may suddenly stop include engine overheating, electrical troubles, mechanical issues, ignition system problems, faulty sensors, and low fuel.
