When to Service Your 1988 Mercedes-Benz 420SEL Cooling System

It can be tough to know when to have your Mercedes-Benz 420SEL radiator serviced if you don't know what it does, but it's still extremely important. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. If your radiator isn’t functioning like it’s supposed to, the engine can overheat – or worse, break down.

Staying on top of routine radiator maintenance for your 1988 Mercedes-Benz 420SEL 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. Visit your local Firestone Complete Auto Care for a Courtesy Check at the first sign of one of these issues.

Mercedes-Benz 420SEL Coolant Fluid Exchange

What’s included in a radiator repair service? 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 then do a machine-powered radiator exchange, replenish flushed chemicals, sealants, and lubricants, and then pressure check for leaks.

If your radiator is acting up, odds are good that your water pump needs to be checked for proper function, too. The water pump is one part on your 1988 Mercedes-Benz 420SEL engine that needs to be addressed ASAP once an issue is identified. This vital part keeps coolant moving through the engine, hoses, and radiator. 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. If you’re about to lose your cool over a too-hot engine, rest assured that we’re here to give your 1988 Mercedes-Benz 420SEL the top-notch service it needs. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.

Common Mercedes-Benz 420SEL Radiator Questions

Wondering how to make your 1988 Mercedes-Benz 420SEL radiator last as long as possible? Read on for answers to common questions, and visit your local Firestone Complete Auto Care when your engine shows any signs of a faulty radiator.

  • What does the coolant light on my Mercedes-Benz dashboard mean? 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.
  • When should my Mercedes-Benz 420SEL 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 420SEL in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.
  • What is causing my 420SEL 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 420SEL engine to overheat.
  • Why does the radiator in my 420SEL sound like it’s rumbling or boiling? Your 420SEL’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!
  • There’s rust in my 420SEL radiator. Should I be worried? Yes. Having rust in your Mercedes-Benz 420SEL 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.
