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.

What are the puddles in my driveway or garage floor?

Notice a leaking fluid that's green, bright orange, or pink and feels sticky? It might be antifreeze. Antifreeze is toxic but has a sweet smell and taste that's attractive to many cats and dogs. Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!

What can cause a 540i radiator to make boiling or rumbling sounds?

There’s rust in my 540i radiator. Should I be worried?

Yes. If you have rust in your BMW 540i radiator, it could cause leaks, negatively impact cooling efficiency, and eventually lead to radiator failure.

When to Service Your 2000 BMW 540i Cooling System

It can be tough to know when to have your BMW 540i radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. 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 2000 BMW 540i is essential for long-term engine health. BMW recommends that you replace coolant (also called antifreeze) at certain 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 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.

What happens during a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your BMW 540i’s cooling system. We’ll do a machine-powered coolant exchange on the system, and then we’ll top off or replace the fluids that were removed (like chemicals, lubricants, and sealants).

Radiator problems often go hand in hand with water pump problems. Of all the parts in your 2000 BMW 540i engine, the water pump is one that you can't put off repairing or replacing.

Our trained technicians can inspect your car’s radiator hoses and pumps to help you stay ahead of any potential engine problems. If you’re about to lose your cool over a too-hot engine, rest assured that we’ll take excellent care of your 2000 BMW 540i at Firestone Complete Auto Care. After all, we know it’s not just a car.
