What does the coolant light on my BMW dashboard mean?

If the coolant light illuminates on your dashboard, your engine could be overheating. Pull over to a safe area and wait for the engine to cool down. Then, head to your nearest Firestone Complete Auto Care for a coolant system check.

Is an antifreeze leak dangerous?

Don’t ignore puddles on your driveway or garage floor. If you see a green, bright orange, or pink fluid puddling under your car (it might be sticky, too), it could be antifreeze that’s leaking out of the engine. Antifreeze has a sweet, attractive smell to cats and dogs (and it’s highly toxic to them), so look out for your pets! Repair any leaks as soon as possible, then carefully wash away any remaining fluid that’s left behind on the driveway or garage floor.

Is It Time for Service on My 2005 BMW 745i Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your BMW 745i radiator serviced, but it's still extremely important. 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.

Staying on top of routine radiator maintenance for your 2005 BMW 745i is crucial to keep your engine in the best possible shape for years to come. BMW recommends that you replace coolant (also called antifreeze) at certain 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 notice a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.
