Hey Guy's -
I know that this horse has been beat to death, I know because I just did a search and read about 50 post's on the topic but still am not sure after reading them all , so here goes.
The car : 1986 944 Turbo (951)
The issue : Which is the low side port ???
The info : I have located two ports capped with plastic covers, so here goes.
Line 1 is located adjacent to the drivers side shock tower and the cap is pointing straight up and has ridges on it. This line is running right next to a similar line, the line with the valve on it is the larger of the two lines.
Line 2 is located down low , you have to look between the drivers side headlight and the radiator to see it, it is positioned on it's side connected to a replacement drier which has the window (the window is showing bubbles) this line is attached to the port marked " IN " on the drier, this is not a factory drier as the PO had it replaced at some point in the car's life, this one is capped with a black cap which has big lug's on it for grip not the small ridges like the cap listed above.
The question : So which is the low or recharge side line ???
