Install the clamp [A] so that the clamp end is about 16
mm (0.63 in.) [B] apart from the pump inlet step. This
prevents coolant leakage from the hose end.
Tighten the hose clamp screw securely.
Water Pump Inspection
Check the water pump drainage outlet hose [A] at the
bottom of the water pump for coolant leakage.
If the mechanical seal is damaged, the coolant leaks
through the seal and drain through the passage. Replace
the mechanical seal.
Visually inspect the impeller [A].
If the surface is corroded, or if the blades are damaged,
replace the impeller.
Mechanical Seal Replacement
Remove the water pump impeller (see Water Pump Re-
moval in this chapter).
Pry the mechanical seal flange off with a small chisel [A].
Pull the mechanical seal out of the right crankcase with
needle nose pliers. Discard the mechanical seal.
Be careful not to damage the water pump shaft and
the inner sealing surface of the crankcase.
Since the replacement mechanical seal has an adhe-
sive coated body, do not apply a liquid gasket to the
exterior surface of the body.
Press [A] the mechanical seal [B] by using a suitable 28
mm socket [C] and a bearing driver [D] until its flange
touches the step [E].
