What does the coolant light on my Mercedes-Benz dashboard mean?

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.

What are the puddles in my driveway or garage floor?

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.

Can Mercedes-Benz GL450 radiators be cleaned?

It could be a good idea to have your Mercedes-Benz GL450 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 GL450 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 GL450 engine to overheat.

What is making my GL450 radiator sound like it’s boiling or rumbling?

Air pockets in your GL450’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 GL450 radiator. Should I be worried?

Yes. Having rust in your Mercedes-Benz GL450 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.

Is It Time for Service on My 2012 Mercedes-Benz GL450 Cooling System?

It can be tough to know when to have your Mercedes-Benz GL450 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.

Staying on top of routine radiator maintenance for your 2012 Mercedes-Benz GL450 is a huge factor in the longevity of your engine. 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 see coolant leaks under your car, high engine temperatures, or a dashboard light that indicates low coolant. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

Radiator Repair Service for Your Mercedes-Benz GL450

What happens during a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Mercedes-Benz GL450 cooling system. We then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too.

From the heater core to the radiator cap, your 2012 Mercedes-Benz GL450 is in good hands at Firestone Complete Auto Care.
