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?

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.

Your BMW 740i engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.

Why does the radiator in my 740i sound like it’s rumbling or boiling?

Is it bad to have rust on my 740i radiator?

Yes. Rust in the radiator of your BMW 740i 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 2018 BMW 740i Cooling System

It can be tough to know when to have your BMW 740i radiator serviced if you don't know what it does, but it’s vital to know what to look for. Your radiator is part of the cooling system. It helps regulate engine temperature. When the radiator isn't working properly, your engine can overheat and potentially break down.

Staying on top of routine radiator maintenance for your 2018 BMW 740i is essential for long-term engine health. BMW recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. 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.

BMW 740i Coolant Fluid Exchange

What happens during a radiator repair service? When you come to Firestone Complete Auto Care, we’ll begin your radiator repair with an in-depth inspection of the cooling system in your BMW 740i. 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). Lastly, we’ll perform a pressure check to look for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. Some services for your 2018 BMW 740i engine can wait, but the water pump is one part that you'll want to have repaired or replaced as soon as you discover a problem with it. This vital part keeps coolant moving through the engine, hoses, and radiator. 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 you stay ahead of any potential engine problems. From the heater core to the radiator cap, we’ll take excellent care of your 2018 BMW 740i at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.
