How to service the thermostat housing for the 2.3L engine on 2004 Ford Focus?

Service of the 2.3L engine thermostat housing starts with draining the cooling system. Place the car in neutral and hoist it before you remove the accessory drive belt from the system. Start the procedure by taking off the two retaining nuts which attach the power steering hose brackets and setting the hose assemblies alongside the brackets. The service starts with fan motor removal followed by shroud removal and then the process of unbolting the four compressor bolts to relocate the compressor. By releasing spring clips that secure the coolant hoses you should disconnect them from the thermostat housing. The procedure requires you to first remove both bolts attaching the thermostat housing before extracting the thermostat combination unit. Add lubricating engine coolant to the O-ring on the thermostat housing before its installation. The process ends by performing removal steps in reverse and then filling and bleeding the cooling system.
