WATER PUMP INSTALLATION

1. INSTALL WATER PUMP
(a) Remove any oil packing (FIPG) material and be careful not to drop any oil on the contact surfaces of the water pump and cylinder block.
- 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 water pump as shown.
Seal packing: Part No. 08826-00100 or equivalent
- Install a nozzle that has been cut to a 2 - 3mm (0.08 - 0.12 in.) opening.
- Parts must be assembled within 5 minutes of application. Otherwise the material must be removed and reapplied.
- Immediately remove the nozzle from the tube and reinstall the cap.

(e) Connect the water pump to the water by-pass pipe end.
(f) Install the water pump with the nut, 5 bolts and 2 stud bolts. Uniformly tighten the bolts, stud bolts and nut in several passes.
