Air Conditioning
Happy Thursday everyone. On my 83 f150 5.8 truck, the air conditioning has stopped blowing cold air. After inspecting, it looks like I have a larger port (with a blue cap) on the left side of the engine and a smaller cap that looks like it was installed on the truck when made. The question I have is has the ac been converted to r134 knowing this information?

The best is since it sounds like it needs a charge in my opinion is to. drain out the oil from the compressor buy a new filter/drier add a pag oil evacuate system & charge with 134A.
But first make sure the compressor is good. Ford compressors fail & are prone to Black Death. If your oil or freon is black then you have a much bigger job in front of you.

really depends on the compressor if he has a dealer A/C unit after 1982 installed or a pre '82 factory ac system using the York Techumsa compressor then the oil is the least of the worries as the York style of compressor has a sump to lube the compressor so oil swap is not necessary as the oil does not flow with the refrigerant like it would on a sumpless design. The old A6 GM compressors had a sump as well on the York style and the A6 style I never changed over to Pag oil never even changed the oil to be honest and the A/C has been working for years and years without failiure.
