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?

Don’t ignore puddles on your driveway or garage floor. If you see a green, bright orange, or pink fluid puddling under your car (it might be sticky, too), it could be antifreeze that’s leaking out of the engine. Antifreeze has a sweet, attractive smell to cats and dogs (and it’s highly toxic to them), so look out for your pets! Repair any leaks as soon as possible, then carefully wash away any remaining fluid that’s left behind on the driveway or garage floor.

Do Lexus GS400 radiators need to be cleaned?

It could be a good idea to have your Lexus GS400 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

My GS400 overheated! What can cause that?

If your Lexus GS400 engine overheats, it could be because of a clogged radiator, a damaged thermostat, a faulty cooling fan, a malfunctioning water pump, or low coolant levels.

My GS400 radiator sounds like it's rumbling or boiling! What's up?

There could be air pockets in your GS400’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).

Is it bad to have rust on my GS400 radiator?

Yes. If you have rust in your Lexus GS400 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 1998 Lexus GS400 Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your Lexus GS400 radiator serviced, but it's still extremely important. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. When the radiator isn't working properly, your engine can overheat and potentially break down.

Staying on top of routine radiator maintenance for your 1998 Lexus GS400 is essential for long-term engine health. Lexus recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. You could be on the verge of a radiator-induced 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. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

What to Expect from Lexus GS400 Radiator Repair

What does radiator repair include? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Lexus GS400’s cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. The water pump is one part on your 1998 Lexus GS400 engine that you'll want to have repaired or replaced as soon as you discover a problem with it. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. If it’s not working well (or at all), your engine can easily overheat. Let our technicians examine your radiator pumps and hoses to help you stay ahead of any potential engine problems. From the heater core to the radiator cap, we’ll take excellent care of your 1998 Lexus GS400 at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.
