Mercury Mountaineer Thermostats

Why you drive your Mountaineer.

When your Mercury Mountaineer was born, it was destined for a driver who prioritizes long-lasting quality in their automobile. Anyone who operates a Mercury knows that when it comes to maintaining their vehicle only the absolute best replacement parts will do. You picked your Mountaineer because its reliability and a trusted name agreed with your nature; so why would you settle for second rate when it comes to superior quality auto parts? Mercury car, truck, or SUV drivers have grown accustomed to a certain level of high-value when driving their Mountaineer around town.

Why Thermostats replacement is so important.

Your car or truck uses liquid coolant to maintain a constant temperature in the engine, and its thermostat keeps the coolant flowing in the right direction so that your engine can maintain a constant and ideal operating temperature. 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 the right temperature, your Mercury Mountaineer thermostat then opens up and allows the coolant into the radiator. Now your coolant is part of a constant cycle in your Mercury Mountaineer engine that keeps it within a specific range of temperatures that are ideal for engine performance... all thanks to the thermostat.
