Why does the check engine light in my CT4 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 CT4 firing up its circuits. The light should turn off in a bit, but come see us if it doesn't.

Why is my Cadillac CT4 making engine noise?

Strange under-the-hood noises can point to problems within your Cadillac CT4 engine. Tapping or knocking could mean you need an oil change. A high-pitched whistle could signal an intake leak or misaligned belt. Squealing can indicate a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.

What could damage my Cadillac CT4 engine?

Some driving habits are not so great for your engine. These include driving on a near-empty gas tank, revving the engine while still 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.

Is it okay to put water in my Cadillac CT4 radiator?

While it’s not recommended, you can use water in your CT4 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 CT4 to suddenly stop?

Your CT4 car engine could stop suddenly due to low fuel, electrical issues, overheating, a faulty ignition system, mechanical troubles, or sensor problems.
