When Does My 2021 Mercedes-Benz CLS450 Radiator Need Service?

It can be tough to know when to have your Mercedes-Benz CLS450 radiator serviced if you don't know what it does, but 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 2021 Mercedes-Benz CLS450 is a huge factor in the longevity of your engine. To keep your radiator functioning, Mercedes-Benz 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. Your radiator could be close to causing an 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. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

What to Expect from Mercedes-Benz CLS450 Radiator Repair

What does radiator repair include? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Mercedes-Benz CLS450 cooling system. We’ll do a machine-powered coolant exchange on the system, and then we’ll top off or replace the fluids that were removed (like chemicals, lubricants, and sealants). Lastly, we’ll perform a pressure check to look for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. Of all the parts in your 2021 Mercedes-Benz CLS450 engine, the water pump is one that you'll want to have repaired or replaced as soon as you discover a problem with it. This vital part keeps coolant moving through the engine, hoses, and radiator. If it’s not working well (or at all), your engine can easily overheat. Let our technicians examine your radiator pumps and hoses to help you stay ahead of any potential engine problems. If you’re about to lose your cool over a too-hot engine, rest assured that we’ll take excellent care of your 2021 Mercedes-Benz CLS450 at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Mercedes-Benz CLS450 Radiator Q&A

Take care of your 2021 Mercedes-Benz CLS450 radiator and it will last. Check out our top questions and answers about Mercedes-Benz radiators below, and visit your nearest Firestone Complete Auto Care at the first sign of an overheating engine.

  • Why is the coolant light on my Mercedes-Benz dashboard on? 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? 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!
  • When should my Mercedes-Benz CLS450 radiator be cleaned? It could be a good idea to have your Mercedes-Benz CLS450 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 CLS450 to overheat? One of the main reasons your Mercedes-Benz CLS450 engine might overheat is because you don’t have enough coolant. Other causes include a clogged radiator, a damaged cooling fan, a malfunctioning thermostat, or a faulty water pump.
  • What is making my CLS450 radiator sound like it’s boiling or rumbling? There could be air pockets in your CLS450’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).
  • Is it bad to have rust on my CLS450 radiator? Yes. Rust in your Mercedes-Benz CLS450 radiator could reduce cooling efficiency, cause leaks, and even lead to radiator failure. Left unchecked, rust can damage the radiator's cooling passages causing small holes or cracks in the radiator. Maintain your radiator system to help prevent rust.
