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

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.

What are the puddles in my driveway or garage floor?

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 S400 radiator be cleaned?

It could be a good idea to have your Mercedes-Benz S400 radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.

My S400 overheated! What can cause that?

If your Mercedes-Benz S400 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.

Why does the radiator in my S400 sound like it’s rumbling or boiling?

There could be air pockets in your S400’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).

There’s rust in my S400 radiator. Should I be worried?

Yes. Having rust in your Mercedes-Benz S400 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 2011 Mercedes-Benz S400 Cooling System?

It can be tough to know when to have your Mercedes-Benz S400 radiator serviced if you don't know what it does, but it’s vital to know what to look for. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. When the radiator isn't working properly, your engine can overheat and potentially break down.

Keeping up with regular radiator maintenance in your 2011 Mercedes-Benz S400 is crucial to keep your engine in the best possible shape for years to come. To keep your radiator functioning, Mercedes-Benz recommends replacing your antifreeze or coolant at scheduled intervals but it’s a good idea to keep your eyes open for any indication that your radiator is failing. 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. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.
