Shop Ford Explorer Replacement Thermostat Housing

The thermostat housing of your Ford Explorer can crack or become damaged. Thermostat housings are responsible for holding the engine's thermostat. The housing also supplies the coolant to your Ford Explorer's radiator. A cracked thermostat housing can leak coolant through the gasket which will affect the operation of the radiator in your vehicle. Any suspicion that your thermostat housing may be damaged, should be verified by a mechanic. A thermostat housing should be replaced immediately, if it is found to be damaged.

A thermostat housing unit for a Ford Explorer can be expensive, especially if you purchase one locally at a car shop. You should not have to pay high prices to get your car running again. If you do need to replace your Explorer's thermostat housing, you can order one online from the auto parts expert at Parts Geek and have it sent to you.

I as somewhat skeptical to buy this unit due to the low price, which included the upper and lower housing, plus the thermostat was included, but it has worked perfect. I saved $100 off the dealership price. - Great housing
