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.

Can an antifreeze leak wait?

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!

Do BMW M3 radiators need to be cleaned?

It could be a good idea to have your BMW M3 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

What can cause my M3 to overheat?

If your BMW M3 engine overheats, it could be because of a clogged radiator, a damaged thermostat, a faulty cooling fan, a malfunctioning water pump, or low coolant levels.

My M3 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 M3. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

There’s rust in my M3 radiator. Should I be worried?

Yes. Rust in the radiator of your BMW M3 can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator. Over time, rust can eat away at the radiator's cooling passages, forming tiny holes or cracks that can affect its operation. To help prevent rust from causing damage, you should stay on top of radiator maintenance.

Is It Time for Service on My 2018 BMW M3 Cooling System?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your BMW M3 radiator serviced. Nonetheless, 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 M3 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 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. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.
