What does an illuminated coolant temperature light mean for my BMW?

Pay attention to the temperature gauge and lights on your dashboard. If a low coolant warning light comes on or your dashboard temperature gauge keeps rising, it’s likely that your engine is about to overheat (and could leave you stranded on the road). Wait for the engine to cool down, then have your coolant system checked immediately at your nearest Firestone Complete Auto Care.

To help prevent rust from causing damage, you should stay on top of radiator maintenance.

When to Service Your 1991 BMW M3 Cooling System

It can be tough to know when to have your BMW M3 radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Regular, proactive service on the radiator in your 1991 BMW M3 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 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.
