Why does the check engine light come on when I start my Yukon XL 1500?

Generally, your check engine light turning on upon ignition is not a bad thing. This is a sign that your vehicle is testing its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.

Why is my GMC Yukon XL 1500 making engine noise?

Unusual noises can signal a problem with your GMC Yukon XL 1500 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 be traced back to 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 Yukon XL 1500 engine?

Certain driving habits can damage your engine and should be avoided. These habits include 'running on fumes,' revving your engine while the vehicle is in Park, or slamming the gas pedal while the engine is still cold. Help sustain your engine’s performance and efficiency by staying miles away from these bad driving practices.

Can I put water in my GMC Yukon XL 1500 radiator?

An emergency is the only time you should consider putting water in your radiator. Outside of that, it’s recommended you use a pre-mixed coolant or a 50/50 blend of water and coolant. However, if you need to continue driving your Yukon XL 1500 when you’re out of coolant, having water in the coolant reservoir is better than nothing.

What can cause the engine in my Yukon XL 1500 to suddenly stop?

Reasons your Yukon XL 1500 car engine may suddenly stop include engine overheating, electrical troubles, mechanical issues, ignition system problems, faulty sensors, and low fuel.
