Why is my Buick Park Avenue making engine noise?

Unusual noises can signal a problem with your Buick Park Avenue engine. Tapping or knocking could mean you need an oil change. Whistling could mean a belt is misaligned or there's an intake leak. Squealing may be caused by a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.

What could damage my Buick Park Avenue engine?

Can I add water to my Buick Park Avenue 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.

Why did my Park Avenue engine suddenly stop?
