Why is the coolant light on my Mercedes-Benz dashboard on?

Your engine might be about to overheat. If your low coolant light is on, pull over in a safe area and wait for your engine temperature to go down. Once it’s safe to do so, bring your car to your nearest Firestone Complete Auto Care to have the coolant system inspected.

Can an antifreeze leak wait?

It's better to get it fixed sooner than later. Antifreeze is toxic if consumed, but its smell can attract cats and dogs. Keep your whole family safe by repairing antifreeze leaks ASAP and thoroughly hosing down your parking spot to get rid of any lingering residue on the ground.

When should my Mercedes-Benz G550 radiator be cleaned?

It could be a good idea to have your Mercedes-Benz G550 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

My G550 overheated! What can cause that?

If your Mercedes-Benz G550 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.

What is making my G550 radiator sound like it’s boiling or rumbling?

Air pockets in your G550’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 G550 radiator?

Yes. Having rust in your Mercedes-Benz G550 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 G550 Cooling System

It can be tough to know when to have your Mercedes-Benz G550 radiator serviced if you don't know what it does, 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. 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 2020 Mercedes-Benz G550 is essential for long-term engine health. Mercedes-Benz recommends that you replace coolant (also called antifreeze) at certain intervals, but you can also take note of any signs your radiator is going bad. You might be driving around (or about to be stranded) with a failing radiator 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. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.
