xtremerevolution Posted April 18, 2009 Report Share Posted April 18, 2009 i'm dirty as shit working on my car right now trying to fix a/c. where the hell does that orifice tube go?

Addicted To Boost Posted April 18, 2009 Report Share Posted April 18, 2009 Good question, I would like to know this as well. Quote Link to comment Share on other sites More sharing options...
Crazy K Posted April 18, 2009 Report Share Posted April 18, 2009 Below the mastercylinder is a joint in the AC plumbing. it goes there. Quote Link to comment Share on other sites More sharing options...

xtremerevolution Posted April 19, 2009 Author Report Share Posted April 19, 2009 Yep, I figured it out. The fitting connect was covered up by a bunch of wiring so I didn't see it. A/C blows ice cold (seriously) for the first time in 2 years. The orifice tube was gunked and clogged up beyond belief. I used two cans of pag oil and two cans of refrigerant. I'll let you guys know the size of those cans later. I replaced all of the o-rings I could find after having disconnected all of the plumbing in the engine bay, and also replaced the accumulator. It was a surprisingly easy job, although time consuming. Quote Link to comment Share on other sites More sharing options...
xtremerevolution Posted April 19, 2009 Author Report Share Posted April 19, 2009 One other thing. Does the passenger fan always kick on when the A/C turns on? Or is it only after a certain temperature? The fan worked before, but I didn't notice it turn on at any point while the A/C was on. Granted, the temperature read under the half mark the whole time as well. Its been too long since the A/C worked for me to remember if its supposed to turn on all the time or not.

Yes, that is normal. Awesome! I was getting a bit scared that I'd have to get my hands dirty tomorrow. Today was 80 degrees, tomorrow is supposed to be 85, and Monday is supposed to hit 88. If I get sent to the San Fernando Valley to do work like I do every now and then, the temperatures easily hit 90 degrees which feels more like 100 degrees if you're sitting in traffic. Does anyone know how much refrigerant is supposed to be in this system? Or should I just keep filling it up until it reaches a certain pressure point? How much pressure should there be in the system? After adding two cans of refrigerant and two cans of PAG oil with the compressor running, I'm sitting at 20PSI. Quote Link to comment Share on other sites More sharing options...
95 vert Posted April 19, 2009 Report Share Posted April 19, 2009 Around 2 pounds of freon IIRC Quote Link to comment Share on other sites More sharing options...
1990lumina Posted April 19, 2009 Report Share Posted April 19, 2009 There should be a sticker somewhere in the engine bay saying how much to put in. Quote Link to comment Share on other sites More sharing options...
3pt1lumina Posted April 19, 2009 Report Share Posted April 19, 2009 2 lbs I believe Quote Link to comment Share on other sites More sharing options...

xtremerevolution Posted April 20, 2009 Author Report Share Posted April 20, 2009 so the cans I put in were 13oz, and 2 lb is 32oz, so I went and got a third can and filled up the system with that, making it 39oz total. pressure is consistent at 45psi, which is still well in the green on the psi gauge. its been 80 degrees all day and the air blows ice cold, as it should, so i'm happy.
