What does an illuminated coolant temperature light mean for my Lexus?

Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.

What are the puddles in my driveway or garage floor?

It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.

Do Lexus SC400 radiators need to be cleaned?

It could be a good idea to have your Lexus SC400 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

My SC400 overheated! What can cause that?

One of the main reasons your Lexus SC400 engine might overheat is because you don’t have enough coolant. Other causes include a clogged radiator, a damaged cooling fan, a malfunctioning thermostat, or a faulty water pump.

What can cause a SC400 radiator to make boiling or rumbling sounds?

Air pockets in your SC400’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.

Is it bad to have rust on my SC400 radiator?

Yes. If you have rust in your Lexus SC400 radiator, it could cause leaks, negatively impact cooling efficiency, and eventually lead to radiator failure. Left unaddressed, radiator rust can erode the cooling passages, creating cracks or small holes. Properly maintaining your radiator system can help stop it from rusting.

When to Service Your 1999 Lexus SC400 Cooling System

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Lexus SC400 radiator serviced. Nonetheless, it’s vital to know what to look for. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Staying on top of routine radiator maintenance for your 1999 Lexus SC400 is essential for long-term engine health. Lexus recommends that you replace coolant (also called antifreeze) at certain intervals, but you can also take note of any signs your radiator is going bad. Your radiator could be close to causing an engine breakdown if you notice a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.
