Andrew Posted May 17, 2007 Report Share Posted May 17, 2007 So i bought one of those ac recharge cans with an inline guage. anyway, on my l36, the only AC port i can find is right behind the airbox, but im guessing this is not the right one, as the fitting wont go on it. and i tried hard!! so am i just SOL on doing it myself or is there a AC port that i overlooked? its like this can on the left.

digitaloutsider Posted May 17, 2007 Report Share Posted May 17, 2007 All cars use the same ports, as far as I know. You must be overlooking something. Let me run out and look at the Regal. Edit: Try the one on the firewall. Quote Link to comment Share on other sites More sharing options...
Andrew Posted May 18, 2007 Author Report Share Posted May 18, 2007 oh snap! i just went and looked and saw it right away. how the hell did i miss that before? i know why, cuz i was thinking it was closer to the compressor. anyway, will do it in the morning. i was trying the one by #1. http://65.175.136.163:9001/servlets/BlobShtml?ShtmlFile=314314&pubid=78&evc=sm Quote Link to comment Share on other sites More sharing options...

GnatGoSplat Posted May 18, 2007 Report Share Posted May 18, 2007 Were you trying the high pressure port? It's a good thing you didn't succeed if that's the case. That's pressurized up to 200psi! I don't know if those refill cans could handle 200psi of pressure, but I wouldn't want to find out. Quote Link to comment Share on other sites More sharing options...
slick Posted May 18, 2007 Report Share Posted May 18, 2007 Nope, definately can't handle that type of pressure! Anyways, I've use those before with great results. In fact, I'm about to check my Bonneville and Rachels 95 Regal this weekend. Quote Link to comment Share on other sites More sharing options...
greencutlassdrvr Posted May 18, 2007 Report Share Posted May 18, 2007 it wont fit on the high pressure side the nipple is to big... the r134a recharge hose will only fit on the low side smaller nipple Quote Link to comment Share on other sites More sharing options...
Andrew Posted May 19, 2007 Author Report Share Posted May 19, 2007 welp i did it yesterday. piece o cake. i was right at 25 psi which is the lowest of being in the good region of 25-45. so i unloaded that can in it and it only went up like 5 psi, but it sure blows colder!!

NVMY03GT Posted May 25, 2007 Report Share Posted May 25, 2007 What type of refrigerant does a 1995 GP SE use ? R12 or !34a? So can someone give me a picture of where I hook the line up to? Compressor is still functioning and AC is blowing just warmer than I like Quote Link to comment Share on other sites More sharing options...
slick Posted May 25, 2007 Report Share Posted May 25, 2007 IIRC, it will be under/beside your airbox on the drivers side of the engine bay. Quote Link to comment Share on other sites More sharing options...

Also - What size bolt is that airBox bolt holding it in because I don't get the little bastard. Forgoing are we R12 or R134a? Quote Link to comment Share on other sites More sharing options...

leman Posted June 26, 2007 Report Share Posted June 26, 2007 I have a 92 gp and the person before me ripped out the condenssor in the front of the rad, so i want to replace it as well as the o-rings for all the connections. but i am not shure how to test the compressor to see if it pumps or even turns with the motor. I live in canada and we dont have these charging kits as far as i know. Where do you get them. Do they come in r12 also, or just the 134a.

slick Posted June 26, 2007 Report Share Posted June 26, 2007 Only in R134a. You *should* be able to test a compressor just by giving it 12v and a ground. IIRC, it's just a two pin connector. Quote Link to comment Share on other sites More sharing options...

Part Source sells a version of Freeze 12 (different name though, can't remember) It's compatible with both R12 and R134a systems..FWIW Quote Link to comment Share on other sites More sharing options...

Part Source sells a version of Freeze 12 (different name though, can't remember) It's compatible with both R12 and R134a systems..FWIW There is no refrigerant/additive that is compatible with r12 AND r134a. R12 and R134a use different types of oils, and they're way different types of refrigerants. 134a can be used in a system that was designed for r12 because their temperature-pressure relationships are almost identical. But, you need to completely remove the r12 and all of its oil before charging 134a and its oil into the system. If the two types of refrigerants and/or oils are allowed to combine, they will create an acid that will destroy your system from the inside out. I need to figue out how to recharge my mom's Tahoe. Is everything fundamentally the same on most cars? Yes Only in R134a. You *should* be able to test a compressor just by giving it 12v and a ground. IIRC, it's just a two pin connector. I'm not entirely sure on this, but do automobile compressors have the high and low pressure switches built into the compressor? If they're built in and wired internally, putting 12V on the clutch shouldn't do anything if that low pressure switch is open. I could be wrong though.

Thnaks Be sure to use a vacuum pump on your system before charging, you've gotta boil off any water in the system because that will react with the oil and create an acid too.

Puggsley456 Posted July 11, 2007 Report Share Posted July 11, 2007 Its odd that your presure only went up a little. I bought one of those cans form walmart and it may have been a bit larger. But my ac was totally empty and it filled it right to 45psi. But Damn the AC draws alot of current. It draws more than my 1500rms stereo does at full tilt.

Schurkey Posted July 14, 2007 Report Share Posted July 14, 2007 1. You cannot legally buy or sell R-12 without being certified/licensed. The good news is that the certification is super-easy. 2. My '93 Euro 3.4 has both high side and low side fittings under the air box. What moron decided that was a good place? Took about a half-pound. I bought the car a couple of years ago, and have no idea on it's service history. 3. My '92 Euro 3.4 has been in the family since late 92. I've never had to top off the refrigerant in 14+ years. Might be getting close to needing it, though. Quote Link to comment Share on other sites More sharing options...
