MAINTENANCE
For the use of the special wrench, see the figure.
1.
By using the special wrench, loosen ring (3) of KCCV ven-
tilator (1).
2.
After ring (3) comes off, remove case (4) from body (2) and remove element (5).
There may be oil accumulated or sticking in the case and
element. Take care not to spill the oil when replacing the
element.
REMARK
When the ambient temperature is low, water or emulsified
matter may stick to the inside of KCCV because of con-
densation of water vapor in the blowby gas. However, if
the coolant level is normal, it is not a problem.

Remove used O-ring (6) sticking to case (4) and install a new O-ring contained in the service kit.
