jadecuir Posted May 17, 2005 Share Posted May 17, 2005 A friend was recharging my AC system last night. He was not familiar with lexus, but has lots of AC background (navy, Nuc pwr plant, etc.) When he tried to pull a vacuum, He could only pull to -30 lbs, then it pulsated. Then we found the other low-side valve. I think we were pulling air in via that valve. Car was previously diagnosed at an independent shop as having bad comp, but after partial charge and oil, we had 200 lbs on high side, 30 on low. Cold air again! Question is, does anyone have the PDF section of the manual on hand? I'm away from my home computer, and I want to show my friend the specifics on the system: recharge procedures, capacities, etc. Also, there were no caps on the three fittings. Shouldn't there be caps? John D Quote Link to comment Share on other sites More sharing options...
pachocco1 Posted May 17, 2005 Share Posted May 17, 2005 Caps are a good preventitive measure. In my experience, the valves tend to leak very slowly over time if uncapped. coolings.pdf Quote Link to comment Share on other sites More sharing options...

jadecuir Posted May 18, 2005 Author Share Posted May 18, 2005 Just an update: Yesterday I got some caps, and we vacuumed the system, after running it with oil/dye and r-22 half charge. With caps in place, it held vacuum! Charged with Honduran R-12, and we're cold again! Watchin' for leaks, John Quote Link to comment Share on other sites More sharing options...
