What does the coolant light on my BMW dashboard mean?

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 to Service Your 2023 BMW 740i Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your BMW 740i radiator serviced, but it's still extremely important. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Keeping up with regular radiator maintenance in your 2023 BMW 740i is crucial to keep your engine in the best possible shape for years to come. BMW recommends that you replace coolant (also called antifreeze) at certain intervals, but you can also take note of any signs your radiator is going bad. Your radiator could be close to causing an engine breakdown if you see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.
