When Does My 1990 Mercedes-Benz 420SEL Radiator Need Service?

If you’re not sure what the purpose of a radiator is, it’s hard to tell when to have your Mercedes-Benz 420SEL radiator serviced. Nonetheless, you need to know the signs of radiator malfunction. Your radiator is part of the cooling system. It helps regulate engine temperature. When the radiator isn't working properly, your engine can overheat and potentially break down.

Staying on top of routine radiator maintenance for your 1990 Mercedes-Benz 420SEL is crucial to keep your engine in the best possible shape for years to come. In fact, Mercedes-Benz recommends replacing coolant/antifreeze at specific 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 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.

Radiator Repair Service for Your Mercedes-Benz 420SEL

What does radiator repair include? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Mercedes-Benz 420SEL’s cooling system. We’ll do a machine-powered coolant exchange on the system, and then we’ll top off or replace the fluids that were removed (like chemicals, lubricants, and sealants). Lastly, we’ll perform a pressure check to look for leaks.

Radiator problems often go hand in hand with water pump problems. Of all the parts in your 1990 Mercedes-Benz 420SEL engine, the water pump is one that you can't put off repairing or replacing. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. If it isn’t functioning properly, your engine won’t be able to stay within its optimal temperature range. Let our technicians examine your radiator pumps and hoses to ensure everything is operating as it should. When it comes to radiator service and repair, we’ll take excellent care of your 1990 Mercedes-Benz 420SEL at Firestone Complete Auto Care. After all, we know it’s not just a car. It’s your car.

Questions About Mercedes-Benz 420SEL Radiators

Take care of your 1990 Mercedes-Benz 420SEL radiator and it will last. Check out our top questions and answers about Mercedes-Benz radiators below, and visit your nearest Firestone Complete Auto Care at the first sign of an overheating engine.

  • Why is the coolant light on my Mercedes-Benz dashboard on? 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.
  • Can an antifreeze leak wait? 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 420SEL radiator be cleaned? To keep your Mercedes-Benz 420SEL radiator running well, it’s wise to get it cleaned out a few times a year.
  • Why is my 420SEL overheating? One of the main reasons your Mercedes-Benz 420SEL 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.
  • My 420SEL radiator sounds like it's rumbling or boiling! What's up? If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your 420SEL. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
  • Should I be concerned about rust in my 420SEL radiator? Yes. Rust in the radiator of your Mercedes-Benz 420SEL can impair its cooling efficiency, cause leaks, and even result in complete failure of the radiator. Over time, rust can eat away at the radiator's cooling passages, forming tiny holes or cracks that can affect its operation. To help prevent rust from causing damage, you should stay on top of radiator maintenance.
