Cooling system hoses
The following precautions MUST be followed to
ensure that integrity of cooling hoses and their
connections to system components are
maintained.
Hose orientation and connection
Correct orientation of cooling hoses is important in
ensuring that the hose does not become fatigued or
damaged through contact with adjacent
components. Where 'timing' marks are provided on
the hose and corresponding connection, these must
be used to ensure correct orientation. Hoses must be
pushed fully onto their connection points. Usually, a
moulded form on the stub pipe provides a positive
indicator.
Hose clips
Markings are usually provided on the hose to indicate
the correct clip position. If no markings are provided,
position the clip directly behind the retaining lip at the
end of the stub as shown. Worm drive clips should be
oriented with the crimped side of the drive housing
facing towards the end of the hose, or the hose may
become pinched between the clip and the stub pipe
retaining lip. Worm drive clips should be tightened to
3 Nm (2 lbf.ft) unless otherwise stated. Ensure that
hose clips do not foul adjacent components.
'Oetiker' clips may be removed by bending the tag
(arrowed) and releasing the free end of the clip. Clips
must not be re-used. When fitting new clips, ensure
clip is correctly positioned on hose before tightening
and ensure that when clip is tightened, the tag is
located in longitudinal slot in free end of clip (arrowed
in illustration).
