What does the coolant light on my BMW dashboard mean?

Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.

What are the puddles in my driveway or garage floor?

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.

Do BMW 540i radiators need to be cleaned?

Yes. Having rust in your BMW 540i radiator can cause leaks, a reduction in cooling efficiency, and even radiator failure.

To help prevent rust from becoming a major issue, it's important to properly maintain your radiator system.

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your BMW 540i radiator serviced. Nonetheless, you need to know the signs of radiator malfunction.

Keeping up with regular radiator maintenance in your 2003 BMW 540i 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.
