When to Service Your 1998 Mercedes-Benz S420 Cooling System

It can be tough to know when to have your Mercedes-Benz S420 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. When the radiator isn't working properly, your engine can overheat and potentially break down.

Keeping up with regular radiator maintenance in your 1998 Mercedes-Benz S420 is a huge factor in the longevity of your engine. 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. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

Radiator problems often go hand in hand with water pump problems. The water pump is one part on your 1998 Mercedes-Benz S420 engine that you can't put off repairing or replacing. This vital part keeps coolant moving through the engine, hoses, and radiator. If it’s not working well (or at all), your engine can easily overheat.

From the radiator cap to the heater core, your 1998 Mercedes-Benz S420 is in good hands at Firestone Complete Auto Care.

Questions About Mercedes-Benz S420 Radiators

Take care of your 1998 Mercedes-Benz S420 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? 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? 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.
  • Can Mercedes-Benz S420 radiators be cleaned? To keep your Mercedes-Benz S420 radiator running well, it’s wise to get it cleaned out a few times a year.
  • What is causing my S420 to overheat? If your Mercedes-Benz S420 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.
  • What can cause a S420 radiator to make boiling or rumbling sounds? Your S420’s cooling system could contain air pockets or your radiator might be clogged. Another possibility is a faulty radiator cap, which is an easy fix!
  • Should I be concerned about rust in my S420 radiator? Yes. Rust in the radiator of your Mercedes-Benz S420 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.
