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

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.

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 S350 radiator be cleaned?

It could be a good idea to have your Mercedes-Benz S350 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

My S350 overheated! What can cause that?

Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Mercedes-Benz S350 engine to overheat.

Why does the radiator in my S350 sound like it’s rumbling or boiling?

Air pockets in your S350’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 S350 radiator?

Yes. Having rust in your Mercedes-Benz S350 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 2012 Mercedes-Benz S350 Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your Mercedes-Benz S350 radiator serviced, but it's still extremely important. Your radiator is part of the cooling system. It helps regulate engine temperature. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Staying on top of routine radiator maintenance for your 2012 Mercedes-Benz S350 is crucial to keep your engine in the best possible shape for years to come. 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. You could be on the verge of a radiator-induced engine breakdown if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

What to Expect from Mercedes-Benz S350 Radiator Repair

What’s included in a radiator repair service? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Mercedes-Benz S350’s cooling system.

From the heater core to the radiator cap, we’re here to give your 2012 Mercedes-Benz S350 the top-notch service it needs. After all, we know it’s not just a car. It’s your car.
