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

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.

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.

When should my BMW 740i radiator 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?

What can cause a 740i radiator to make boiling or rumbling sounds?

Air pockets in your 740i’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.

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

Yes. Having rust in your BMW 740i 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 740i radiator serviced. Nonetheless, it's still extremely important.

You guessed it – your engine overheats, and it may even break down completely.

Staying on top of routine radiator maintenance for your 2000 BMW 740i is essential for long-term engine health. 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.
