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).
Oil may be accumulated in or sticking to the case and ele-
ment. When replacing the element, take care that the oil
will not spill out.
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 body label, insert the element firmly into the
end of the body.
When inserting, take extreme care so that tooth (9) of the
element is joined together with rubber lip (10) of the ele-
ment.
