Mercury Monarch Thermostats

Your Monarch is a prized possession.

Select Your VehicleIt's not a regular occurrence that you discover you need a replacement Thermostats to repair your vehicle. Obviously, you didn't buy your Monarch unless you knew that you wanted strength and a dash of luxury both rolled up into one automobile. Mercury vehicle enthusiasts have grown accustomed to a certain level of reliability when driving their Monarch around town. When your Mercury Monarch rolled off the assembly line, it was destined for a person with discerning taste who wants a trusted name in their automobile.

Don't go too long without fixing your Thermostats... here's why.

Your car or truck has a liquid-cooled engine, and the device that controls the flow of coolant so that the engine can remain cool is your thermostat. On start-up, the thermostat remains closed; shutting off access to the radiator. This gets the coolant hot so that the engine warms up. Once it reaches an ideal temperature, your Mercury Monarch thermostat responds by directing coolant to the radiator. Now your coolant is part of a constant cycle in your Mercury Monarch engine that keeps it at a steady and controlled temperature ideal for engine performance... all thanks to the thermostat.

We carry thousands of items to choose from.
