Ford F8RZ-8575-CA
Thermostat

The first task of servicing or fixing the thermostat requires draining the cooling system followed by disconnection of all thermostat hoses. The first step includes removing the thermostat cover by unscrewing its three mounting bolts and extracting both the bolts and cover. You should remove the thermostat after completing the first step. The installation steps for the thermostat include performing all removal operations in reverse order followed by cooling system oil replenishment.

Service and repair of the thermostat begins with disconnecting the battery ground cable followed by removing the air cleaner outlet tube. Operator should drain the engine coolant until it reaches a level which stays below the water thermostat (8575). The maintenance work requires removal of electrical connectors that belong to the water temperature indicator sender unit and engine coolant temperature sensor. Start by removing the upper radiator hose combined with the heater coolant hose from the water thermostat housing before removing its bolts followed by the housing unit along with the water thermostat. Make sure to clean all gasket surfaces from old material before sliding the tabs into the proper slots of the thermostat housing during installation. Apply the opposite steps used for removing the components to install them. You should insert Ford Premium Engine Coolant E2FZ-19549-AA (Oregon uses F5FZ-19549-CC and Canada uses Motorcraft CXC-8-B) along with other products that meet Ford specification ESE-M97B44-A through a blend of 50% water and coolant. Thoroughly analyze all hoses and connections for leaks before starting the engine while enabling it to reach normal operating temperature after the water thermostat becomes operational. At the conclusion of the process drive the vehicle to stop and add coolant to the recovery tank only when the liquid reaches the minimum cold fill mark.

Stop the engine and top off the coolant recovery reservoir as needed to maintain the minimum cold fill level.

Reverse the removal procedure for installation.

Allow the engine to warm up until the water thermostat opens, then stop the engine and top off the coolant recovery reservoir as necessary to maintain the minimum cold fill level.
