Why does my SC430’s check engine light come on when I start it?

Generally, your check engine light turning on upon ignition is not a bad thing. This is just your SC430 testing its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.

Why does my Lexus engine sound different?

Unusual noises can signal a problem with your Lexus SC430 engine. Knocking or tapping could be a symptom of low oil. A high-pitched whistle could signal 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 Lexus SC430 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 slamming the gas pedal while the engine is still cold. Steer clear of these habits to help protect engine performance and efficiency.

Is it okay to put water in my Lexus SC430 radiator?

An emergency is the only time you should consider putting water in your radiator. Outside of that, it’s recommended you use a pre-mixed coolant or a 50/50 blend of water and coolant. However, if you need to continue driving your SC430 when you’re out of coolant, having water in the coolant reservoir is better than nothing.

What could cause my SC430 engine to suddenly stop?

There are different reasons your SC430 vehicle engine could suddenly stop. You may be looking at a lack of fuel, faulty sensors, issues with the ignition system, engine overheating, electrical problems, or mechanical troubles.
