Do Mercedes-Benz GLS450 radiators need to be cleaned?

It could be a good idea to have your Mercedes-Benz GLS450 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 GLS450 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 GLS450 engine to overheat.

What is making my GLS450 radiator sound like it’s boiling or rumbling?

Air pockets in your GLS450’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 GLS450 radiator bad?

Yes. Having rust in your Mercedes-Benz GLS450 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 2020 Mercedes-Benz GLS450 Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your Mercedes-Benz GLS450 radiator serviced, but you need to know the signs of radiator malfunction. 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 2020 Mercedes-Benz GLS450 is essential for long-term engine health. In fact, Mercedes-Benz recommends replacing coolant/antifreeze at specific 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 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.
