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

Generally, your check engine light turning on upon ignition is not a bad thing. It’s just your Grand Wagoneer firing up its circuits. The light should turn off in a bit, but come see us if it doesn't.

Why is my Jeep Grand Wagoneer making engine noise?

Unusual noises can signal a problem with your Jeep Grand Wagoneer engine. 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 could be a sign that something is wrong with your brakes — not the engine.

What could damage my Jeep Grand Wagoneer 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. Steer clear of these habits to help protect engine performance and efficiency.

Can I add water to my Jeep Grand Wagoneer radiator?

While it’s not recommended, you can use water in your Grand Wagoneer radiator in emergencies. Normally, you should only use a 50/50 mix of coolant and water or a pre-mixed coolant. However, if you are completely out of coolant and must continue driving, it’s better to have water in your coolant reservoir than nothing.

What can cause the engine in my Grand Wagoneer to suddenly stop?

Your Grand Wagoneer car engine could stop suddenly due to low fuel, electrical issues, overheating, a faulty ignition system, mechanical troubles, or sensor problems.
