SteveH Posted July 16, 2011 Report Share Posted July 16, 2011 Where is the low pressure service valve located on a 96 pontiac grand se with 3.1L motor to refill the r-134a freon? Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted July 16, 2011 Report Share Posted July 16, 2011 look around the airbox, you'll find both of them in the area, i believe the low pressure side is the one that's furthest down. Quote Link to comment Share on other sites More sharing options...
SteveH Posted July 16, 2011 Author Report Share Posted July 16, 2011 Can I just remove the air box to recharge the freon? Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted July 16, 2011 Report Share Posted July 16, 2011 yes, it's actually the only way i could even get my hands in there. it's not like you'll be driving around with it off. Quote Link to comment Share on other sites More sharing options...
virtuetovice Posted July 16, 2011 Report Share Posted July 16, 2011 x2, the air box is definitely in the way unless you have cat-sized paws and you're made of rubber . FYI, the charge hose will not connect to the high side, it will ONLY connect to the low side. Quote Link to comment Share on other sites More sharing options...
