When Does My 2003 Lexus IS300 Radiator Need Service?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Lexus IS300 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. So, what happens when the radiator isn’t working quite like it should? You guessed it – your engine overheats, and it may even break down completely.

Regular, proactive service on the radiator in your 2003 Lexus IS300 is crucial to keep your engine in the best possible shape for years to come. In fact, Lexus recommends replacing coolant/antifreeze at specific intervals, but it’s also wise to keep an eye out for signs of a failing radiator. You might be driving around (or about to be stranded) with a failing radiator if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.
