When to Service Your 1986 Mercury Grand Marquis Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your Mercury Grand Marquis radiator serviced, 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 1986 Mercury Grand Marquis is a huge factor in the longevity of your engine. Mercury recommends that you replace coolant (also called antifreeze) at certain intervals, but you can also take note of any signs your radiator is going bad. 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. As soon as you see one of these symptoms, come to your nearest Firestone Complete Auto Care for a Courtesy Check.

What to Expect from Mercury Grand Marquis Radiator Repair

What does radiator repair include? If you bring your vehicle to Firestone Complete Auto Care, we start with a comprehensive inspection of your Mercury Grand Marquis’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.

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 Mercury Grand Marquis engine, the water pump is one that needs to be addressed ASAP once an issue is identified. The role of the water pump is to keep coolant circulating in your engine, radiator, and hoses. Without it, your engine won't maintain its optimal temperature. Let our technicians examine your radiator pumps and hoses to ensure everything is operating as it should. From the radiator cap to the heater core, we’ll take excellent care of your 1986 Mercury Grand Marquis at Firestone Complete Auto Care. We stand behind our work with our Triple Promise: Fixed Right, Priced Right, Right on Time.

Mercury Grand Marquis Radiator Q&A

Take care of your 1986 Mercury Grand Marquis radiator and it will last. Check out our top questions and answers about Mercury radiators below, and visit your nearest Firestone Complete Auto Care at the first sign of an overheating engine.

  • What does the coolant light on my Mercury 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? Notice a leaking fluid that's green, bright orange, or pink and feels sticky? It might be antifreeze. Antifreeze is toxic but has a sweet smell and taste that's attractive to many cats and dogs. Do your pets a favor and have an antifreeze leak investigated ASAP. Then hose down the driveway or garage floor!
  • Do Mercury Grand Marquis radiators need to be cleaned? It could be a good idea to have your Mercury Grand Marquis radiator cleaned out a couple of times a year, maybe at the same time as a tire rotation or oil change.
  • What can cause my Grand Marquis to overheat? Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Mercury Grand Marquis engine to overheat.
  • What is making my Grand Marquis radiator sound like it’s boiling or rumbling? There could be air pockets in your Grand Marquis’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).
  • Is rust in my Grand Marquis radiator bad? Yes. If you have rust in your Mercury Grand Marquis 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.
