Using a properly lubricated O-ring, connect the #6 A/C hose to the #6 condenser hardline (See Photo 42, Page
18, and Figure 1, Page 9).
From where it exits the firewall, route the #10 A/C hose to the compressor. Temporarily attach the 135° fitting
to the compressor. Cut the hose to the proper length, and connect the hose to the compressor fitting. Mark the
fitting and hose to ensure proper positioning, and remove the fitting from the compressor. Crimp the fitting
onto the hose, and permanently connect to the compressor using a properly lubricated O-ring (See Photos 44
& 45, below, and Figure 1, Page 9).
Using a properly lubricated O-ring, connect the 90° fitting on the #8 A/C hose to the #8 condenser hardline.
From there, route the #8 hose to the compressor. Temporarily attach the 135° fitting to the compressor. Cut
the hose to the proper length, and connect the hose to the compressor fitting. Mark the fitting and hose to
ensure proper positioning, and remove the fitting from the compressor. Crimp the fitting onto the hose, and
permanently connect to the compressor using a properly lubricated O-ring (See Photos 44 & 45, below, and
Figure 1, Page 9).
Connect the heater hose from the heater control valve to the water neck. Secure with a hose clamp (See Photo
46, below).
Connect the remaining heater hose to the water pump. Secure with a hose clamp (See Photo 46, below).
NOTE: On 6-cylinder engine compartments, there are multiple possibilities for routing the #8 and #10
A/C hoses, depending the installer’s preference. For this reason, the #8 and #10 hoses are shipped
with fittings installed on one end only. The other end will need to be cut and crimped after routing has
been determined. For our installation, Vintage Air’s technicians routed the hoses beneath the engine,
securing them to the front frame crossmember with (2) #10 Adel clamps as shown below.
