Point1
[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 installation part to the
cylinder block 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.)
Point2
[Disassemble]
• Check the thermostat function. See 2.7 in Chapter 2
for the inspection method.
