Are you going by "feel" or actual measurements? The typical difference is so minute, that a human cannot discern the difference. If you could actually feel a difference, chances are something isn't operating 100% and causing reduced performance.Originally Posted by 19Cutlass94

the difference is quite large actually. I believe the output from the vent is 5 to 10* colder with R12. You can convert a R12 system to R134 because they run on at the same ambient temperature and internal pressures.

my gp doesnt blow out cold at all but its not really hot.. maybe just a charge?

Joey, speaking from my own experience, there isn't a whole lot of difference. The last R134a converted cars(1988 Chevrolet pickup & an older Ford T-bird) that I've bothered to measure vent outlet temperatures on were 38*F to 40*F when the ambient temperature was around 85*F. I haven't measured an R12 car in a while, but I honestly cannot "feel" a difference between my TGP with R12 and my other GP that hs R134a in it. I'll measure vent temperatures on both soon...they both blow ice cold!Originally Posted by joey b
Shadow, here's the picture.
The one with the blue cap there is the low side port that you'll need to use for recharging. Your caps are likely black in color if your car hasn't been converted yet.

They change the caps when they retrofit?

You have screw on R134a fittings when you retrofit and the kits that the fittings come in usually have red & blue color coded caps with them to designate the high(red) and low(blue) sides from one another. The stock caps are typically just black in color.Originally Posted by 5speedz34

Ya, I knew they where black. Our cars are easy to recharge which is nice not having to dig for caps.
