Is It Time for Service on My 1986 Mercedes-Benz 420SEL Cooling System?

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, it’s vital to know what to look for. As part of your car’s cooling system, your radiator helps keep engine temperature regulated. 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.

Regular, proactive service on the radiator in your 1986 Mercedes-Benz 420SEL is essential for long-term engine health. To keep your radiator functioning, Mercedes-Benz recommends replacing your antifreeze or coolant at scheduled intervals but it’s also wise to keep an eye out for signs of a failing radiator. You could be on the verge of a radiator-induced engine breakdown if you notice a low coolant light or higher-than-normal engine temperatures on your dashboard, or if you spot coolant leaks coming from your car. 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. Of all the parts in your 1986 Mercedes-Benz 420SEL engine, the water pump is one 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. Our trained technicians can inspect your car’s radiator hoses and pumps to help make sure everything is in working order. From the radiator cap to the heater core, your 1986 Mercedes-Benz 420SEL is in good hands at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.

Mercedes-Benz 420SEL Radiator Q&A

Wondering how to make your 1986 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 an illuminated coolant temperature light mean for my Mercedes-Benz? 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.
  • Is an antifreeze leak dangerous? 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? It could be a good idea to have your Mercedes-Benz 420SEL radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
  • My 420SEL overheated! What can cause that? If your Mercedes-Benz 420SEL 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.
  • My 420SEL radiator sounds like it's rumbling or boiling! What's up? There could be air pockets in your 420SEL’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).
  • There’s rust in my 420SEL radiator. Should I be worried? Yes. If you have rust in your Mercedes-Benz 420SEL radiator, it could cause leaks, negatively impact cooling efficiency, and eventually lead to radiator failure. Left unaddressed, radiator rust can erode the cooling passages, creating cracks or small holes. Properly maintaining your radiator system can help stop it from rusting.
