Mercury Custom Thermostats

Why you drive your Custom.

The vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles on the road today. You purchased your Custom because its reliability and long-lasting quality appealed to your senses; so why would you settle for anything but the best when it comes to great quality auto parts? While it may not be difficult to buy replacement parts for Mercury vehicles, these days only the highest quality are required to repair your car or truck. Your Mercury dealership isn't the only place to find trusted parts to repair your Custom.

What Thermostats does for your vehicle.

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; bypassing the flow of coolant through your radiator. This gets the coolant hot so that the engine warms up. Once it reaches an optimal operating temperature, your Mercury Custom thermostat responds by directing coolant to the radiator. Now your coolant is part of a constant cycle in your Mercury Custom engine that keeps it at a steady and controlled temperature ideal for engine performance... all thanks to the thermostat.

Good products, great prices, the best people.
