(d) Install the water pump and a new gasket with the 5 bolts, 2 stud bolts and nut. Uniformly tighten the bolts, stud bolts and nut in several passes.

Torque:

21 N·m {214 kgf·cm, 15ft·lbf} for bolt

18 N·m {194 kgf·cm, 24ft·lbf} for nut and stud bolt

HINT:

Use bolts 35 mm (1.38 in.) in length.

2. INSTALL WATER INLET HOUSING

(a) Remove any old packing (FIPG) material and be careful not to drop any oil on the contact surfaces of the water inlet housing and water pump.

HINT:

  • Using a razor blade and gasket scraper, remove all the old packing (FIPG) material from the gasket surfaces 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 the water inlet housing as shown in the illustration.

Seal packing:

Part No. 08826-00100 or equivalent

Seal diameter:

2 to 3 mm (0.078 to 0.118 in.)

HINT:

  • Use a nozzle that has opening of 2 to 3 mm (0.08 to 0.12 in.).
  • Parts must be assembled within 5 minutes of application. Otherwise the material must be removed and reapplied.
  • Immediately remove nozzle from the tube and reinstall cap after application.

(c) Install a new O-ring to the water inlet housing.

(d) Apply soapy water on the O-ring.
