- Disconnect the negative battery cable.
- If equipped, disconnect the rubber retainer that engages the wiring harness to the radiator hose.
- Tag and disengage all electrical connections that would interfere with thermostat removal.
- Remove the radiator cap.
- Place a suitable container under the radiator petcock, open the petcock and drain the coolant until it is at a level below the upper radiator hose, then close the petcock.
- Loosen the upper radiator hose-to-thermostat housing (water hose connection) clamp, then disconnect the hose from the housing.
- Loosen the housing retaining nut and bolt, and remove the housing.
- Remove the thermostat and the old gasket.
- Use a scraper to clean any old gasket material residue from the housing and the cylinder head mating surfaces.
- Install the thermostat in the cylinder head, valve end first and the subvalve at the top.
- Coat the new gasket with a sealing compound such as B5A-19554-A, F2AZ-19554-AA or their equivalents, and install the gasket on the cylinder head, making sure the holes are properly aligned in relation to the bolt hole and stud.
- Install the thermostat housing carefully so that the gasket will remain in position.
Make sure the thermostat flange is seated properly into the recess in the housing before tightening the retainers.
- Install the nut and bolt. Tighten them to 14-19 ft. lbs. (19-26 Nm).
- Connect the upper radiator hose to the thermostat housing and tighten the hose clamp.
- Fill the cooling system to the proper level and install the radiator cap.
- Connect the negative battery cable and start the car.
- Let the engine reach normal operating temperature, then check for leaks and proper thermostat operation.
