INSPECTION





1. INSPECT WATER PUMP
a) Visually check the drain hole for coolant leakage.
If leakage is found, replace the water pump.
If engine coolant has leaked onto the timing belt, replace the timing belt.
b) Turn the pulley, and check that the water pump bearing moves smoothly and quietly.
If necessary, replace the water pump.
2. INSPECT FLUID COUPLING





a) Remove the 4 nuts and fan from the fluid coupling.





b) Check that the fluid coupling is not damaged and that no silicon oil leaks.
If necessary, replace the fluid coupling.
c) Reinstall the fan to the fluid coupling with the 4 nuts.

^ 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 groove 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 inch) opening.
^ 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.
c) Install the water pump with the 7 bolts.
