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

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.

Can an antifreeze leak wait?

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.

Do Mercury Mariner radiators need to be cleaned?

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

What can cause my Mariner to overheat?

Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Mercury Mariner engine to overheat.

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

There could be air pockets in your Mariner’s cooling system. You might also have a clogged radiator or faulty radiator cap (this last one is an easy fix!).

Should I be concerned about rust in my Mariner radiator?

Yes. Having rust in your Mercury Mariner 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.

When Does My 2005 Mercury Mariner Radiator Need Service?

Not sure what a radiator does? That makes it difficult to know when to have your Mercury Mariner radiator serviced, but you need to know the signs of radiator malfunction. 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 2005 Mercury Mariner is a huge factor in the longevity of your engine. Mercury recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. Your radiator could be close to causing an engine breakdown if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light. When you experience one or more of these issues, head to your local Firestone Complete Auto Care for a Courtesy Check.

Radiator Repair Service for Your Mercury Mariner

What’s included in a radiator repair service? At Firestone Complete Auto Care, we start by performing a thorough inspection of your Mercury Mariner 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. Of all the parts in your 2005 Mercury Mariner engine, the water pump is one 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. Without it, your engine won't maintain its optimal temperature.

From the heater core to the radiator cap, we’re here to give your 2005 Mercury Mariner the top-notch service it needs. After all, we know it’s not just a car. It’s your car.
