91GPSTE Posted June 16, 2005 Report Share Posted June 16, 2005 I replaced an evaporator on my GP and I want to refill it with freon but have to get the entire system vacuumed. It has been converted to R134. Anyone know how I would go about doing this? Quote Link to comment Share on other sites More sharing options...
DiscoStudd Posted June 16, 2005 Report Share Posted June 16, 2005 Buy a vacuum pump (JC Whitney sells them) or take it to a shop to get it evacuated. I'd go with option #2 because those vac pumps that JC Shitney sells (last I checked) cost over 2 bills... Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted June 16, 2005 Report Share Posted June 16, 2005 I bought this one on Ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=53300&item=7523880023&rd=1&ssPageName=WD1V It's pricey, but I wanted my A/C to work. More importantly than that, my wife wanted the A/C to work! Quote Link to comment Share on other sites More sharing options...
KingArthur Posted June 18, 2005 Report Share Posted June 18, 2005 If you have a AutoZone in your town, go rent one. Thats what I did... it cost $200 for a deposit but you get that back after you return the pump. My A/C is super cool now. I also change the GM white orfice tube to Ford blue orfice tube to make the compressor pull more vaccum at low rpm. Quote Link to comment Share on other sites More sharing options...

I had to borrow one off from one of my neighbors. Quote Link to comment Share on other sites More sharing options...

Now when the family ride in my car they complain that their too cold. Quote Link to comment Share on other sites More sharing options...
91GPSTE Posted June 18, 2005 Author Report Share Posted June 18, 2005 I got a pump from a friend today. Will have to see how to hook it up to the fitting now. I wonder if a fitting from the refill kit will work. Hopefully it is not only 1 way. Quote Link to comment Share on other sites More sharing options...
