Why does the check engine light in my LeSabre turn on when I start my car?

Generally, your check engine light turning on upon ignition is not a bad thing. It’s just your LeSabre firing up its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.

Why is my Buick LeSabre making engine noise?

Strange under-the-hood noises can point to problems within your Buick LeSabre 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 might be a sign of brake problems rather than engine issues.

What could damage my Buick LeSabre engine?

Certain driving habits can hurt your engine. These habits include driving on an empty fuel tank, flooring the gas pedal while the car is in Park, or slamming the gas pedal while the engine is still cold. Help sustain your engine’s performance and efficiency by staying miles away from these bad driving practices.

Can I add water to my Buick LeSabre radiator?

While it’s not recommended, you can use water in your LeSabre 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 could cause my LeSabre engine to suddenly stop?

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