Why does the check engine light come on when I start my SC400?

Whistling could mean a belt is misaligned or there's an intake leak. Squealing may be caused by a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.

Can I add water to 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.
