1.
Reinstall all previously removed items.
Fill radiator with at least a 50/50 mixture of approved antifreeze and distilled water. It is the owner’s
responsibility to keep the freeze protection at the proper level for the climate in which the vehicle is operated.
Failure to follow antifreeze recommendations will cause heater core to corrode prematurely and possibly burst
in A/C mode and/or freezing weather, voiding your warranty.
Double check all fittings, brackets and belts for tightness.
Vintage Air recommends that all A/C systems be serviced by a licensed automotive A/C technician.
Evacuate the system for a minimum of 45 minutes prior to charging, and perform a leak check prior to
servicing.
Charge the system to the capacities stated on Page 4 of this instruction manual.
See Operation of Controls procedures on Page 26.
Locate the evaporator drain on the bottom of the evaporator case. In line with the drain, drill a 5/8” hole
through the floor where it meets the firewall (See Photos 1 & 2, below). Cut a 3” to 4” piece of drain hose,
and connect it to the 1/2” 90° elbow. Connect the long piece of drain hose to the 90° elbow. From inside
the truck, push the tail end of the drain hose through the hole in the floorboard. With the elbow against the
firewall, measure and cut the hose, and then push it onto the evaporator drain pan fitting. Ensure that the
hose from the drain pan has adequate drop to allow drainage (See Photo 3, below). On the engine side of the
firewall, cut the hose and install the second 90° elbow. Attach the remaining hose to the elbow, and route
to drain below the cab (See Photo 4, below). Seal with silicone around the hose at the floorboard to prevent
water from coming in.
