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

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.

Do Mercury Cougar radiators need to 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 Mercury Cougar in for routine maintenance or service, it could be a good idea to opt for a radiator cleaning, too.

What is causing my Cougar to overheat?

If your Mercury Cougar 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.

Why does the radiator in my Cougar sound like it’s rumbling or boiling?

Air pockets in your Cougar’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.

Is it bad to have rust on my Cougar radiator?

Yes. Having rust in your Mercury Cougar 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 to Service Your 1991 Mercury Cougar Cooling System

Not sure what a radiator does? That makes it difficult to know when to have your Mercury Cougar 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. When the radiator isn't working properly, your engine can overheat and potentially break down.

Keeping up with regular radiator maintenance in your 1991 Mercury Cougar is crucial to keep your engine in the best possible shape for years to come. Mercury 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. You might be driving around (or about to be stranded) with a failing radiator 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.
