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.

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.

Can Mercedes-Benz CLS550 radiators 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 Mercedes-Benz CLS550 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.

My CLS550 overheated! What can cause that?

If your Mercedes-Benz CLS550 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 CLS550 radiator sounds like it's rumbling or boiling! What's up?

Air pockets in your CLS550’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.

Should I be concerned about rust in my CLS550 radiator?

Yes. Having rust in your Mercedes-Benz CLS550 radiator can cause leaks, a reduction in cooling efficiency, and even radiator failure. If rust is left untreated, it can corrode the radiator's cooling passages, causing small cracks or holes that can significantly impact the radiator's ability to function. To help prevent rust from becoming a major issue, it's important to properly maintain your radiator system.

When to Service Your 2009 Mercedes-Benz CLS550 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 CLS550 radiator serviced. Nonetheless, 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. 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 2009 Mercedes-Benz CLS550 is a huge factor in the longevity of your engine. Mercedes-Benz 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 might be driving around (or about to be stranded) with a failing radiator if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.
