What does an illuminated coolant temperature light mean for my Mercedes-Benz?

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.

Is an antifreeze leak dangerous?

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 SL450 radiator 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 SL450 in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.

What can cause my SL450 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 SL450 engine to overheat.

Why does the radiator in my SL450 sound like it’s rumbling or boiling?

If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your SL450. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.

Should I be concerned about rust in my SL450 radiator?

Yes. Having rust in your Mercedes-Benz SL450 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 2019 Mercedes-Benz SL450 Cooling System

It can be tough to know when to have your Mercedes-Benz SL450 radiator serviced if you don't know what it does, but you need to know the signs of radiator malfunction. The radiator is in the cooling system of your car, and it helps your engine temperature stay within a safe range. 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 2019 Mercedes-Benz SL450 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 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 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.
