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

Why is my GMC Yukon XL making engine noise?

Strange engine sounds can be a sign something’s off in your GMC Yukon XL. 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 might be a sign of brake problems rather than engine issues.

What could damage my GMC Yukon XL engine?

Certain driving habits can hurt your engine. These habits include driving on an empty fuel tank, flooring the gas pedal while the car is in Park, or pushing 'the pedal to the metal' before the engine has warmed up. Protect your engine’s performance and efficiency by distancing yourself from these habits.

Can I put water in my GMC Yukon XL radiator?

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