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

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 light should go off shortly. Bring your vehicle in if it doesn't.

Why does my Buick engine sound different?

Unusual noises can signal a problem with your Buick Skylark engine. Tapping or knocking could mean you're low on oil. Whistling could mean a belt is misaligned or there's an intake leak. 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 Buick Skylark 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.

Is it okay to put water in my Buick Skylark radiator?

It’s not recommended you put water in your Skylark radiator unless it’s an emergency. Under normal circumstances, use a 50/50 mix of water and coolant or a pre-mixed coolant. But, if you need to keep driving while out of coolant, using water is better than driving with an empty coolant reservoir.

What can cause the engine in my Skylark to suddenly stop?

If your Skylark car engine suddenly stops, it could be due to overheating, low fuel, a faulty ignition system, sensor problems, electrical system trouble, or mechanical issues.
