just measured my explorer.....abiant temp of 82....which makes a HUGE difference. the higher the ambiant to a point, the better your AC works...

anyways....47.56 degrees according to my temp probe that goes in my DVOM.....

Oh...but i have an unfair advantage....my explorer is still R12

muy cousin had '90 ranger and he managed to get his temps from the vents to be 36*. no joke. i didnt believe him till we went to town and he stuck the probe in the vent. bouy the time it hit 40* i was begin him to shut off but he had to prove it. howd he get it that cold?

r-12 is a FAR superior refrigerant to r-134a....i could probably get my explorer down in the high 30's as well given the right ambiant temp......some of it also has to do with the amount of ductwork between the AC evap core and the vents, the less the better...

i've heard of the a/c mod what exactly is it and how do you do it???

In my 85 I could get 42.1 (r-12) and in the sploder I get 54.0 (r-12) also measured with a DVOM

54 seems a little warm for r12, was it a cooler day??? sounds like the 85 is workin well though

[fordnut85]

Well that was while it was in my shop and I would assume it was about 75 in there. Yeah, the 85 will darn near frost the windows, but then again I'm a Wyoming boy in the middle of kansas summer so it's just about right lol

A/C mod. the only ones with a "kit" as far i know to do it.

All that kit does is put a shut-off valve in your coolant supply lines to the heater core. Not hard to do yourself and can get the parts at a local hardware store.
