When to Service Your 2003 Mercedes-Benz SL55 AMG Cooling System

It can be tough to know when to have your Mercedes-Benz SL55 AMG radiator serviced if you don't know what it does, but 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 Mercedes-Benz SL55 AMG is essential for long-term engine health. In fact, Mercedes-Benz recommends replacing coolant/antifreeze at specific 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 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.
