hey guys so i just picked myself up a 1990 7mgte supra and the a/c is not working atm, the belt was off the compressor when i bought it so something must be wring with the system. SO what i was wondering was that the high side port with the red cap between the bumper and the front of the engine bay wall or crash bar thing that fitting does not fit on r12 fittings or r134a. i know the system uses r12. is there an adapter piece i can use to do a vacuum test or a nitrogen pressure test?
any advice would be great.
