The source of this noise may be due to direct
contact between adjacent refrigerant lines
(Figure 1) or between a refrigerant line and
the Bowden cable clip for the front hood
release in the front motor compartment
(Figure 2). When the air conditioning
compressor is operating the noise created by
the vibration is transferred from this point of
contact and into the cabin.
Figure 1. The refrigerant lines possibly make contact.

3. These refrigerant lines must be separated
and, if necessary, retained in a separated
position using a hose holder, clip, or tiewrap (Figure 5).

5. An additional point of contact may be
found between the refrigerant line
containing the service port and the clip
that retains the Bowden cable for the
front hood release. If contact is found
here these components must be
separated and secured in a separated
position. The retaining clip for the
refrigerant line allows the line to slide
within it. This is to be considered when
securing the line away from the clip for
the Bowden cable.
Figure 7. Point of contact between refrigerant line and Bowden
cable clip.
6. Figure 8 shows an additional point of
contact possible at the coaxial refrigerant
line where it crosses the refrigerant line
containing the service port. Again,
separate and secure these lines in a
separated position.
