What does the coolant light on my Mercedes-Benz dashboard mean?

Pay attention to the temperature gauge and lights on your dashboard. If a low coolant warning light comes on or your dashboard temperature gauge keeps rising, it’s likely that your engine is about to overheat (and could leave you stranded on the road). Wait for the engine to cool down, then have your coolant system checked immediately at your nearest Firestone Complete Auto Care.

Is an antifreeze leak dangerous?

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.

Do Mercedes-Benz CLS400 radiators need to be cleaned?

My CLS400 radiator sounds like it's rumbling or boiling! What's up?

Is rust in my CLS400 radiator bad?

Yes. Rust in the radiator of your Mercedes-Benz CLS400 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 2016 Mercedes-Benz CLS400 Cooling System

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Mercedes-Benz CLS400 radiator serviced. Nonetheless, you need to know the signs of radiator malfunction. 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.

Regular, proactive service on the radiator in your 2016 Mercedes-Benz CLS400 is crucial to keep your engine in the best possible shape for years to come. In fact, Mercedes-Benz recommends replacing coolant/antifreeze at specific intervals, but you can also take note of any signs your radiator is going bad. You might be driving around (or about to be stranded) with a failing radiator 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.
