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

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.

Can an antifreeze leak wait?

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 bad to have rust on my 740iL radiator?

Yes. Rust in the radiator of your BMW 740iL can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator.

To help prevent rust from causing damage, you should stay on top of radiator maintenance.

When to Service Your 2000 BMW 740iL Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your BMW 740iL radiator serviced, but it’s vital to know what to look for. Your radiator is part of the cooling system. It helps regulate engine temperature. So, what happens when the radiator isn’t working quite like it should? You guessed it – your engine overheats, and it may even break down completely.

Keeping up with regular radiator maintenance in your 2000 BMW 740iL is a huge factor in the longevity of your engine. In fact, BMW recommends replacing coolant/antifreeze at specific intervals, but you can also take note of any signs your radiator is going bad. You could be on the verge of a radiator-induced engine breakdown if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

BMW 740iL Coolant Fluid Exchange

What happens during a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your BMW 740iL cooling system. Then, we’ll move on to a machine-powered coolant exchange. Finally, we’ll refill the flushed sealants, lubricants and chemicals, then do a pressure check to catch any possible leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. The water pump is one part on your 2000 BMW 740iL engine that you can't put off repairing or replacing. This pump ensures that coolant is always flowing through the radiator, hoses, and engine. If it isn’t functioning properly, your engine won’t be able to stay within its optimal temperature range. Our technicians can take a look at your radiator’s components to help make sure everything is in working order. If you’re about to lose your cool over a too-hot engine, rest assured that your 2000 BMW 740iL is in good hands at Firestone Complete Auto Care. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.
