Ranger Posted June 24, 2005 Report Share Posted June 24, 2005 I went out this morning to ship the vinyl top wax to KHE and it was already almost 90 degrees. I had recently checked and topped off my A/C (thanks to KHE's advice) and all is up to specs. I noticed that the vent temp, while comfortable was not real cold. Now I had serviced my buddies Chrysler a little over a month ago and the vent temps were in the high 30's (granted it was not a 90 deg. day). I decided to check my vent temps and all I could hold was 60 deg. So I checked the manual and it says on a 90 deg. day with high humidity my vent temp should be 70-75 (low side 55-65, high side 310-340). Based on that, the system is performing as well or better than it is supposed to. Out of curiousity I checked the manual for my daughters '99 SLS and it says vent temps should be 44-50 (low side 34-40, high side 190-210) under the same conditions. The '97 has a HD6/HT6 compressor (differences are in the mounting per the manual). I could not find the compressor type in the '99 manual but I am assuming it is the same. So what gives? Why the vast difference in published vent temps and pressures? Link to comment Share on other sites More sharing options...
