What does the coolant light on my BMW dashboard mean?

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.

Is an antifreeze leak dangerous?

It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.

Do BMW 740i radiators need to be cleaned?

It could be a good idea to have your BMW 740i radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

My 740i overheated! What can cause that?

Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your BMW 740i engine to overheat.

My 740i radiator sounds like it's rumbling or boiling! What's up?

If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your 740i. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

There’s rust in my 740i radiator. Should I be worried?

Yes. If you have rust in your BMW 740i radiator, it could cause leaks, negatively impact cooling efficiency, and eventually lead to radiator failure. Left unaddressed, radiator rust can erode the cooling passages, creating cracks or small holes. Properly maintaining your radiator system can help stop it from rusting.

When to Service Your 2015 BMW 740i Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your BMW 740i radiator serviced, 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.

Keeping up with regular radiator maintenance in your 2015 BMW 740i is a huge factor in the longevity of your engine. 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. You could be on the verge of a radiator-induced engine breakdown 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. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.
