TGP AC

[TGPvsTIII]

do not remove it. It is needed. It does have a screen on it but it is also a little tube hense the name oriface. The compressor takes the low pressure gas and compresses it. It is now a high pressure liquid coming out of the compressor. It runs through the condenser to be cooled. It comes out still in liquid form but cooler. it then gets to the ORIFACE tube where it is basicly metered to the low side through the tube and on to the evaporator. This changing of states from liquid to gas is what removes the heat from the air flowing over the evaporator. If you remove the tube the high side gas will just flow uncontrolled to the evaporator and NO cooling will happen. Also your high side gauge reading will drop and the low side will go high. These tubes have differant size openings for differant applications. That is why I said I used a ford blue tube in Jimmys TGP it is a differant size tube. I believe the stock TGP tube is white. Ask Jimmy how his car cooled after the R134 swap with the blue tube. (His isn't working right now because a steel line had a hole rubbed in it (behind the master cylinder) right before repairing his powermaster III and the 5sp swap we just need to charge it up)

Yea what he said, leave the orifice in. It is a required and esential part of the AC system..

As far as what I did, I had a bit more work on mine TGP cause it was previously totaled and wrecked in the front end. I did replace the AC Condensor, as well as the acumlator, and both lines coming off the AC compressor going to the acumalator tank, and condensor. I also replaced the condensor with a diferent model (can be found in the "How do I" section). Vacced it down at a shop, came home, put the fittings on, and converted the SOB to R134a. It leaked out over the first winter cause I accidently put to O-rings in on a connection.
