How to Service and Repair a Thermostat on Ford Explorer?

Partially draining the cooling system constitutes the first step for servicing and repairing the thermostat. Open the upper radiator hose and move the clamp before splitting the water bypass hose from its water hose connection. Securing the water hose connection requires the removal of two bolts yet you should avoid applying force to that area. After draining the cooling system partially you should disconnect the water hose connection and the water thermostat while removing the thermostat gasket before cleaning all mating surfaces. The new thermostat gasket needs application of Gasket and Trim Adhesive F3AZ-19B508-AA or its equivalent substitute before installation. Insert the new thermostat gasket onto the water hose connection after placing the water thermostat correctly inside the connection slot with the notch properly positioned. Refit both the water hose connection along with the water bypass tube before you place the hose clamps correctly and tighten them properly. Complete the process by replacing the upper radiator hose then filling the cooling system.
