INSPECTION
1.
INSPECT WATER PUMP
(a)
Visually check the air hole and water hole for coolant leak-
age.
If leakage is found, replace the water pump and timing belt.

INSTALL WATER INLET AND INLET HOUSING AS-
SEMBLY
(a)
Remove any old packing (FIPG) material and be careful
not to drop any oil on the contact surfaces of the water in-

faces and sealing groove.
Thoroughly clean all components to remove all the
loose material.
Using a non–residue solvent, clean both sealing
surfaces.
(b)
Apply seal packing to the sealing groove of water inlet
housing as shown in the illustration.
Seal packing: Part No. 08826–00100 or equivalent
Install a nozzle that has been cut to a 2 – 3 mm (0.08
– 0.12 in.) opening.
Parts must be assembled within 3 minutes of ap-
plication. Otherwise the material must be removed
and reapplied.
Immediately remove nozzle from the tube and rein-
stall cap.
(c)
Install a new O–ring to the water inlet housing.
(d)
Apply soapy water on the O–ring.
