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.

What are the puddles in my driveway or garage floor?

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 640i radiator be cleaned?

Cleaning your car shouldn’t be limited to the parts you can see. Regular cleaning is good for your radiator, too! When you take your BMW 640i in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.

Why is my 640i overheating?

If your BMW 640i 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.

Why does the radiator in my 640i sound like it’s rumbling or boiling?

There could be air pockets in your 640i’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).

Should I be concerned about rust in my 640i radiator?

Yes. Rust in the radiator of your BMW 640i 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.

When to Service Your 2015 BMW 640i Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your BMW 640i radiator serviced, but it's still extremely important. 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 2015 BMW 640i 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. You might be driving around (or about to be stranded) with a failing radiator 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.
