6.4 Servicing Points
Point 1
Disassemble-Reassemble:
Check to see that the cooling water pump bearing is free from abnormal noise, sticking or play and
water leakage from the bearing. If replacement is necessary, replace the whole cooling water
pump assy.
[NOTICE]
Replace the O-ring of the cooling water pump with
new one when disassembling. And, be sure to use
the special O-ring for each engine model, because
the material is different, although the dimension is
the same as a commercial part. (Refer to the right
figure.)
Point 2
Disassemble:
Check the thermostat function. See 2.7 in
Chapter 2 for the inspection method.
