I did a little looking around and am having seconds thoughts about putting R-134 in my a/c system to recharge it, sources say it is hard on a/c components and doesn't last as long as other alternatives.



Does anyone have some input regarding the use of R-134 or other?

go find a refrigeration company that does refrigeration for plants like icecream and stuff like that. They use R-432 I think. BTW why the hell do you need AC for a convertible? Are you one of those ritzy Mercedes Benz convertible owners who insist you have to have the AC cranked while the TOP is down to stay cool?

Thanks I'll check into it. And no, not necessarily, the road trips i'm planning this summer are in areas of the country where the top will need to be up, 120 degrees in the desert isn't comfortable with the top down, no matter how fast you are going.

R134 works just as good as R12. Problem is that most places dont remove all the lines and blow the old lubicant out with solovant. Then you put new oil in, hook it all back up and usually adjust your pressure switch.



The oils actually disolve into the gas. One mixes with one an not the other. So just putting 134 in a r12 system withoug removing the lubricant and putting in the right stuff will blow out the pump.



I did a buch of conversion back when I was a wrench and they work great.



Good luck

I'd still do it... get my ski goggles out or race helmet and go flying across teh desert. Making sure i have GPS and cell phone reception, lots of duct tape and water.

there is a thermostat on the evaporator core you may be able to adjust/move it, its there to keep the evaporator from freezing, which it wont do with 134a when the outside temp is high. if you need it colder than the you need to find some r12, r134a just isnt as good. you can tell cause a car thats meant for r134 will blow a huge volume of air at you but its not really cold, r134 takes larger heat exhangers which we dont have.
