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.

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.

Do Mercedes-Benz E320 radiators need to be cleaned?

Cleaning your car shouldn’t be limited to the parts you can see. Regular cleaning is good for your radiator, too! When you take your Mercedes-Benz E320 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.

What can cause my E320 to overheat?

One of the main reasons your Mercedes-Benz E320 engine might overheat is because you don’t have enough coolant. Other causes include a clogged radiator, a damaged cooling fan, a malfunctioning thermostat, or a faulty water pump.

Why does the radiator in my E320 sound like it’s rumbling or boiling?

Air pockets in your E320’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 E320 radiator bad?

Yes. Having rust in your Mercedes-Benz E320 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 2004 Mercedes-Benz E320 Cooling System?

It can be tough to know when to have your Mercedes-Benz E320 radiator serviced if you don't know what it does, but it’s vital to know what to look for. Your radiator is part of the cooling system. It helps regulate engine temperature. 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.

Keeping up with regular radiator maintenance in your 2004 Mercedes-Benz E320 is essential for long-term engine health. In fact, Mercedes-Benz recommends replacing coolant/antifreeze at specific 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. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.
