Removal
1. Disconnect the wire from the negative battery terminal.
2. Place a drain pan under the radiator.
3. Remove the radiator cap, put a piece of rubber hose on the drain pipe, open the drain. Drain the liquid from the radiator until the liquid level drops below the level in the water outlet unit housing. Close the drain.
4. On a four-cylinder engine, unscrew the vent plug from the water outlet housing.
5. Loosen the hose clamp and disconnect the upper radiator hose from the water outlet assembly
6. Unscrew the mounting bolts (see pictures) and detach the water outlet unit housing.

Note: If the housing is difficult to remove, tap it gently with a soft-faced hammer or a piece of wood. Do not attempt to lever the housing up, as this may damage the sealing surface and cause leaks.
7. On V6 engines, you can turn the thermostat counterclockwise to remove it from the water outlet assembly (see picture). If it is stuck to the exhaust manifold (V6 engine) or cylinder head (four-cylinder engine), gently pry it up with a small screwdriver (see picture).
Installation
8. Clean off any remaining old gasket and seal from the mating surfaces of the housing and cylinder head, then clean them with a cloth soaked in acetone or solvent.
9. To install the thermostat in a four-cylinder engine, begin by aligning the thermostat tongue with the recess in the water outlet housing; then push the thermostat into place, crimping the gasket. When installing the thermostat on V6 engines, first make sure the check ball valve is at the top, then insert the thermostat into the water outlet housing and turn it clockwise into place (see picture).
10. Apply a thin bead of RTV sealant to both sides of the new gasket, then position it on the body and bolt it in place.
11. Place the water bleeder assembly and gasket in place on the cylinder head or manifold, screw in the bolts. Tighten the bolts to the specified torque.
12. Further installation is carried out in the reverse order of disassembly. Carefully check for possible leaks when the engine is heated to normal operating temperature.
