Why does my GMC engine sound different?

Strange engine sounds can be a sign something’s off in your GMC Envoy. Tapping or knocking could mean you're low on 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 GMC Envoy engine?

These habits include 'running on fumes,' 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 GMC Envoy radiator?
