When Does My 2002 BMW 745i Radiator Need Service?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your BMW 745i radiator serviced. Nonetheless, it's still extremely important. Your radiator is part of the cooling system. It helps regulate engine temperature. 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 2002 BMW 745i is crucial to keep your engine in the best possible shape for years to come. To keep your radiator functioning, BMW 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. You might be driving around (or about to be stranded) with a failing radiator 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.
