When Does My 2023 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 still extremely important. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Regular, proactive service on the radiator in your 2023 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. 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. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

Mercedes-Benz CLS450 Coolant Fluid Exchange

What does radiator repair include? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Mercedes-Benz CLS450 cooling system. Then, we’ll move on to a machine-powered coolant exchange. Finally, we’ll refill the flushed sealants, lubricants and chemicals, then do a pressure check to catch any possible 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 2023 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 pump ensures that coolant is always flowing through the radiator, hoses, and engine. Without it, your engine won't maintain its optimal temperature. Our technicians can take a look at your radiator’s components to ensure everything is operating as it should. If you’re about to lose your cool over a too-hot engine, rest assured that we’ll take excellent care of your 2023 Mercedes-Benz CLS450 at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.

Common Mercedes-Benz CLS450 Radiator Questions

With regular maintenance and service as needed, you could extend the life of your 2023 Mercedes-Benz CLS450 radiator. Get answers to common radiator questions, and head to your nearest Firestone Complete Auto Care as soon as you suspect a radiator issue.

  • What does the coolant light on my Mercedes-Benz dashboard mean? If the coolant light illuminates on your dashboard, your engine could be overheating. Pull over to a safe area and wait for the engine to cool down. Then, head to your nearest Firestone Complete Auto Care for a coolant system check.
  • 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.
  • Do Mercedes-Benz CLS450 radiators need to 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 CLS450 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • What can cause my CLS450 to overheat? Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Mercedes-Benz CLS450 engine to overheat.
  • What is making my CLS450 radiator sound like it’s boiling or rumbling? Air pockets in your CLS450’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.
  • Is rust in my CLS450 radiator bad? Yes. If you have rust in your Mercedes-Benz CLS450 radiator, it could cause leaks, negatively impact cooling efficiency, and eventually lead to radiator failure. Left unaddressed, radiator rust can erode the cooling passages, creating cracks or small holes. Properly maintaining your radiator system can help stop it from rusting.
