• Container to catch the drained oil
• Special wrench for KCCV
The KCCV ventilator is located in the position shown in the fig-
ure.
For the use of the special wrench, see the figure.
1.
Loosen the ring (3) of KCCV ventilator (1) by using the
special wrench.
2.
After the 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.
3.
Remove the used O-ring (6) sticking to the case (4) and in-
stall a new O-ring contained in the service kit.
Apply the engine oil to the new O-ring.
