Why does my SC400’s check engine light come on when I start it?

It’s usually normal for your check engine light to turn on upon ignition. 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 Lexus engine sound different?

Strange under-the-hood noises can point to problems within your Lexus SC400 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 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 Lexus SC400 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.

Can I put water in my Lexus SC400 radiator?

It’s not recommended you put water in your SC400 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.

Why did my SC400 engine suddenly stop?

Reasons your SC400 car engine may suddenly stop include engine overheating, electrical troubles, mechanical issues, ignition system problems, faulty sensors, and low fuel.
