HELP HELP AC question for the smart one out there...

Use ester oil instead. Ester oil is believed to actually seal the non-barrier hoses preventing R-134a from seeping out. Did a conversion on a Grand Marquis 5.0 and got 38 out of the vents.

I will be doing this job on my92 gt. Where I get the kit134 what store I want to this right the first time.

See http://jrichker.stangnet.com/Mustang_tech/R134a_conversion/R134a_conversion.htm for the how to do it.

See http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=3952 for a vacuum pump

the kit in the store will it work.

Keep in mind that your R-134 charge should only be about 75 % of the R-12 charge. I've been doing retro-fits for about three years for Ford, and the reason is that R-134 molecules are much smaller and expand under heat at aviolent rate compared to R-12. It would be easy to overcharge the system, and I know from experience that those 'kits' are very general and are supposed to fit many applications. A normal 5.0 Mustang takes 1.75 lbs of R-12 and should work perfectly with 1.25 lbs of R-134.
Also, the accululator should be replaced because the decessant bag (strainer) inside is soaked with R-12 oil, which will not mix with R-134 oil. Therefore rendering the accumulator almost completely useless.
It sounds like your compressor is trying to freeze up due to lack of oil, which should have had no more than 3 oz of new oil installed, or it is overcharging, due to an overcharge of R-134, or a partially blocked orifice tube. I have seen comressors shut an engine down, and even a compressor that seems to be working perfect, if overcharged, will rob up to 30 horsepower! Something to think about! Good luck.

is the accumulator that thing on the firewall.this going to be my first ac job .so can i use the kit. thanks.my ac com is going on and off with r 12.and 12 is very costly. that why i want to change it to 134.

This whole process seems to be one huge pain in the buttocks. Never the less, I'm considering doing the swap to my 86 (considering that I have to break open the AC anyway for the instalation of my SC). My question is this: Aside from the cost of R12 vs. R134-A, is there any advantage to doing the swap?

never ever use any kind of stopleak in an a/c system because just like cooling system stopleak it stops up everything else and ruins more than it fixes.
