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

It's okay if your check engine light comes on when you first start your vehicle. This is a sign that your vehicle is testing its circuits. The light should turn off in a bit, but come see us if it doesn't.

Why is my Mercury Topaz making engine noise?

Strange engine sounds can be a sign something’s off in your Mercury Topaz. Tapping or knocking could mean you need an oil change. Whistling sounds could mean you have an intake leak or misaligned belt. Squealing may be caused by a loose fan belt, and grinding might be coming from the brakes, not the engine.

What could damage my Mercury Topaz engine?

Certain driving habits can hurt your engine. These habits include driving on an empty fuel tank, revving the engine while still 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 add water to my Mercury Topaz 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 the engine in my Topaz to suddenly stop?

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