1 answer
IF YOUR RE-CHARGING WITH THE R-134 CANS OF FREON THAT CONTAINS THE BLUE FILLER HOSE, YOU CAN ONLY FILL THROUGH THE LOW SIDE. THE FITTING FOR THE HIGH SIDE IS MUCH BIGGER AND WILL NOT FIT. LOCATE THE LOW-SIDE (WILL BE THE ONLY FITTING THE RIGHT SIZE. MOST ARE LOCATED BETWEEN THE FIREWALL AND CONDENSER OR ON THE TOP OF THE DRYER/ACCUMULATOR) REMOVE BLACK OR BLUE CAP AND PUSH HOSE ON. START THE TRUCK, TURN A/C ON HIGH, FAN ON HIGH AND SET TO CABIN RECIRCULATION. OPEN VALVE ON CAN. BE SURE TO OBSERVE SYSTEM CAPACITIES AND NOT TO OVER CHARGE.
