When to Service Your 1996 Lexus LS400 Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your Lexus LS400 radiator serviced, but it's still extremely important. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. 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 1996 Lexus LS400 is crucial to keep your engine in the best possible shape for years to come. 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 leaking coolant, overheating, or an illuminated low coolant dashboard light. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

Some services for your 1996 Lexus LS400 engine can wait, but the water pump is one part that you can't put off repairing or replacing. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. Without it, your engine won't maintain its optimal temperature. Our technicians can take a look at your radiator’s components to help you stay ahead of any potential engine problems. From the heater core to the radiator cap, your 1996 Lexus LS400 is in good hands at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.
