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

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 turn off in a bit, but come see us if it doesn't.

Why is my Buick Century making engine noise?

Strange under-the-hood noises can point to problems within your Buick Century engine. Tapping or knocking could mean you need an oil change. Whistling sounds could mean you have an intake leak or misaligned belt. 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 Century engine?

Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, flooring the gas pedal while the car is in Park, or pushing 'the pedal to the metal' before the engine has warmed up. Help sustain your engine’s performance and efficiency by staying miles away from these bad driving practices.

Can I use water in my Buick Century radiator?

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

Reasons your Century car engine may suddenly stop include engine overheating, electrical troubles, mechanical issues, ignition system problems, faulty sensors, and low fuel.
