When to Service Your 1991 BMW 535i Cooling System

It can be tough to know when to have your BMW 535i radiator serviced if you don't know what it does, but 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.

Staying on top of routine radiator maintenance for your 1991 BMW 535i is essential for long-term engine health. 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. 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. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.
