Is It Time for Service on My 2003 Lexus GS430 Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Lexus GS430 radiator serviced. Nonetheless, it's still extremely important. Your radiator is part of the cooling system. It helps regulate engine temperature. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Regular, proactive service on the radiator in your 2003 Lexus GS430 is essential for long-term engine health. To keep your radiator functioning, Lexus recommends replacing your antifreeze or coolant at scheduled intervals but it’s a good idea to keep your eyes open for any indication that your radiator is failing. Your radiator could be close to causing an engine breakdown if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.
