3.
After ring (3) comes off, remove the case (4) from body (2)
and remove the 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.
4.
Remove the 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.
5.
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.
The element can be installed only when its claws (9) are
correctly inserted in grooves (10) of the filter body. Bases
(11) and (12) are oval. When inserting, take extreme care
so that those bases are matched with each other.

mark (13) on the case with that of
