Why does my V3500’s check engine light come on when I start it?

Why is my GMC V3500 making engine noise?

Strange engine sounds can be a sign something’s off in your GMC V3500. Knocking or tapping could be a symptom of low oil. A high-pitched whistle could signal an intake leak or misaligned belt. Squealing can indicate a loose fan belt, and grinding might be coming from the brakes, not the engine.

What could damage my GMC V3500 engine?

Is it okay to put water in my GMC V3500 radiator?

However, if you need to continue driving your V3500 when you’re out of coolant, having water in the coolant reservoir is better than nothing.
