3. After the cap (3), remove the filter element (5) from the hous-
ing (4).
Oil can collect in the container (4) and in the filter element (5),
or stick to it. If you renew the filter element (5), make sure that
the oil does not spray out.
REMARK
If the ambient temperature is low, water or emulsion can stick to
the inside of the KCCV as a result of water vapour in the blow-by
gas condensing. However, this is not a problem as long as the
coolant level is normal.
4. Coat both O-rings (6) with engine oil and attach them to the
top and bottom of the new filter element. You can install the
filter element with either side up or down.
5. Replace the O-ring (7) with a new one. Coat it with engine oil
and fit the cap (3).
6. Tighten the cap (3) by hand or using the filter wrench as far
as the stop.
7. Install the hose (2) so the hose (3) is at a 45
°
angle and
tighten the piping clamp (1).
Torque (1) = 3.0–3.5 Nm
8. Check the KCCV hoses for leaks, damage and loose piping
clamps, and replace them if necessary.
