Why does the check engine light come on when I start my GLK350?

Generally, your check engine light turning on upon ignition is not a bad thing. This is just your GLK350 testing its circuits. The light should go off shortly. Bring your vehicle in if it doesn't.

Why is my Mercedes-Benz GLK350 making engine noise?

Strange under-the-hood noises can point to problems within your Mercedes-Benz GLK350 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 might be coming from the brakes, not the engine.

What could damage my Mercedes-Benz GLK350 engine?

Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, revving the engine while still in Park, or accelerating too quickly, too soon. Steer clear of these habits to help protect engine performance and efficiency.

Is it okay to put water in my Mercedes-Benz GLK350 radiator?

Only in emergencies. A 50/50 mix of coolant and water (or a pre-mixed) coolant is recommended. However, if you must keep driving when you're out of coolant, it's better to drive with water in your coolant reservoir than nothing.

What can cause a GLK350 engine to suddenly stop?
