Look for line returning from cooler in front of radiator. Trace it until you hit the port.

What is the location of low pressure port on a 1996 eagle vision tsi?


Usually close to the drier in the tube on the low pressure side. Drier looks like an aluminum cylinder about as big around as a soda can and twice as tall with two aluminum tubes coming out of it. The port has a screw off cap to access.

Low side on ranger for the port on the ac


hmm ..if you are looking for the low side air conditioner port .. then locate the condenser (thats in front of and looks like the radiator) .. you will notice two tubes going to that ..one is large the other small .. the small tube is the high pressure side .. the large tube is the low pressure side ... follow the large tube back until you find a cap that covers the low pressure port .. thats where you would fill with new refregerant (r134a) .. if you buy r134a, you can also get a filler hose and gage.. that hose will only hook up to the low pressure port ..it wont fit the high pressure port ...

There are two aluminum tubes coming out of the compressor. The high pressure tube goes to the condensor in front of the radiator. The low pressure tube is the other tube, and the port has a black plastic cap over it, on the low pressure tube.
