Is It Time for Service on My 2012 Mercedes-Benz GL550 Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your Mercedes-Benz GL550 radiator serviced, but it's still extremely important. Your radiator is part of the cooling system. It helps regulate engine temperature. 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.

Regular, proactive service on the radiator in your 2012 Mercedes-Benz GL550 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. 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. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

Mercedes-Benz GL550 Coolant Fluid Exchange

What does radiator repair include? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Mercedes-Benz GL550’s 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.

Radiator problems often go hand in hand with water pump problems. Of all the parts in your 2012 Mercedes-Benz GL550 engine, the water pump is one that you can't put off repairing or replacing. This vital part keeps coolant moving through the engine, hoses, and radiator. Without it, your engine won't maintain its optimal temperature. Our technicians can take a look at your radiator’s components to help you stay ahead of any potential engine problems. From the heater core to the radiator cap, we’ll take excellent care of your 2012 Mercedes-Benz GL550 at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Questions About Mercedes-Benz GL550 Radiators

Take care of your 2012 Mercedes-Benz GL550 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? 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.
  • 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.
  • When should my Mercedes-Benz GL550 radiator be cleaned? To keep your Mercedes-Benz GL550 radiator running well, it’s wise to get it cleaned out a few times a year.
  • What can cause my GL550 to overheat? One of the main reasons your Mercedes-Benz GL550 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.
  • My GL550 radiator sounds like it's rumbling or boiling! What's up? Air pockets in your GL550’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.
  • There’s rust in my GL550 radiator. Should I be worried? Yes. Rust in the radiator of your Mercedes-Benz GL550 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.
