Your Ride: 1997 BMW 528i
HELP 1997 528I Question
OK guys you are the experts. I have a wonderful 1997 Silver Bullet 528i and want to add some 134 to my AC. Please if someone would email me and tell me what is the high pressure inlet and which one is the low pressure inlet. I don't want to make any mistakes. I see two places to add the coolant one is up close to the windshield I think that is the high pressure and the other is much closer to the grill... Please someone post and tell me what one to add the R134 can to.. If you would like to email me directly please feel free to spsullivan@cox.net
The high side is the one by the front grille, the low side is the one by the windshield. And the high side is actually an outlet. You want the low side. You can't get these wrong anyhow, because if you look closer, the fittings are different sizes, and only one- the larger (low side) one will fit your R134a can's nozzle.
