When to Service Your 2004 Mercedes-Benz S430 Cooling System

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Mercedes-Benz S430 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 2004 Mercedes-Benz S430 is crucial to keep your engine in the best possible shape for years to come. In fact, Mercedes-Benz recommends replacing coolant/antifreeze at specific intervals, but you can also take note of any signs your radiator is going bad. Your radiator could be close to causing an 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.
