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, as
far as the coolant level is normal, it is not a problem.
3.
Remove used O-ring (6) sticking to case (4) and install a
new O-ring contained in the service kit.
Apply engine oil to the new O-ring.
4.
While matching
◇
marks (7) of the new element with
◇
mark (8) of the case, insert the element firmly into the end
of the body.
When inserting, take extreme care so that protrusion (9) in
the case is joined together with rubber lip (10) of the ele-
ment.
