Budget underhood AC retrofit.

89on35s said
Well I got the correct expansion valve finally! #6MIO inlet, #8MIO outlet, internally regulated. Napa part number A8262. I also put on a Reman compressor because once I finally get this working I don' need to pump it down to chance a damn compressor! Now I just need to get it charged up and test it out.

One thing I am not sure of is what to do with the brass tube coming out of the top of the expansion valve. I'm sure it' a temperature sensor but I'm not sure if it senses under hood temp for some reason or if it needs to be wrapped around the compressor suction line. Any Body know?

There's a 73 Dodge service manual (came from the guys on here) for free download over at MyMopar if you don't have one.

Start with page 24-47 in the 73 manual...........They are showing the 73 has a well for the sensor tube in the suction line. Normally you want to wrap that and seal it with insulating tape to keep it as close to the suction line temp as possible. "Engine bay heat" is not your friend
