Chevrolet Repair: 2002 Chrevrolet 2500 duramax diesel 4x4 truck, diesel 4x4, black caps

Question
Could you please tell me where to put the freon in my truck? I can't seem to find where it goes.

Answer
Passenger side of truck.  You will see the low pressure line from the accumulator...The big silver thing on the fire wall.  There are two fittings with black caps on them.  Remove the cap that corrosponds to the size fitting on the freon hose
