What does an illuminated coolant temperature light mean for my Mercury?

Pay attention to the temperature gauge and lights on your dashboard. If a low coolant warning light comes on or your dashboard temperature gauge keeps rising, it’s likely that your engine is about to overheat (and could leave you stranded on the road). Wait for the engine to cool down, then have your coolant system checked immediately at your nearest Firestone Complete Auto Care.

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 Mercury Marquis radiator be cleaned?

To keep your Mercury Marquis radiator running well, it’s wise to get it cleaned out a few times a year.

My Marquis overheated! What can cause that?

Your Mercury Marquis engine could overheat due to low coolant, a clogged radiator, a damaged water pump, a malfunctioning cooling fan, or a faulty thermostat.

My Marquis radiator sounds like it's rumbling or boiling! What's up?

Air pockets in your Marquis’s cooling system may cause a rumbling or boiling noise. You could also have a clogged radiator or simply need to replace the radiator cap.

There’s rust in my Marquis radiator. Should I be worried?

Yes. If you have rust in your Mercury 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.

Is It Time for Service on My 1986 Mercury Marquis Cooling System?

Not sure what a radiator does? That makes it difficult to know when to have your Mercury Marquis radiator serviced, but it's still extremely important. 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 1986 Mercury Marquis is crucial to keep your engine in the best possible shape for years to come. To keep your radiator functioning, Mercury recommends replacing your antifreeze or coolant at scheduled intervals but it’s a good idea to keep your eyes open for any indication that your radiator is failing. You might be driving around (or about to be stranded) with a failing radiator 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.

What to Expect from Mercury Marquis Radiator Repair

What happens during a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Mercury Marquis 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.

Issues with your radiator often coincide with a malfunctioning water pump. The water pump is one part on your 1986 Mercury Marquis engine 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. Our trained technicians can inspect your car’s radiator hoses and pumps to ensure everything is operating as it should. When it comes to radiator service and repair, we’ll take excellent care of your 1986 Mercury Marquis at Firestone Complete Auto Care. Every job we do is backed by our Triple Promise: Fixed Right, Priced Right, Right on Time.
