I have installed the new retro kit of 134a but it doesnt get very cold.
i tried to vaccum down the system to zero but dont know if i actually accomplished that task didnt really have an adequate guage. and anyone advise on the exact proceedure to make this happen. i have a 1988 dodge ram 100 4 by 4 pickup.
thanks

I have converted many a vehicle to R-134. 99 percent of them turned out cold enough to knock your nipples off. Of course, I worked in a professional shop with the proper equipment. Trucks usually have beefier systems and the general design of a truck lends it to have better airflow over the condenser because of their large grilles. so, tell me exactly what you did to vacuum it down with and why you dont have a set of ac guages if you have a vacuum pump. There are 100 things that can go wrong during a conversion if you dont know how the system works. Did you kow that if you dont get all the R-12 oil out then there is 8 ounces of space that you didn't fill up with R-134. I've even mixed oils and they ran great but you have to know how to compensate. PS. FIND OUT WHERE YOUR r-12 LEAKED OUT OF BEFORE YOU CHARGE THE SYSTEM AGAIN. they are sealed systems and shold not need a recharge unless something is broken. russellp73@gmail for more info.

i cant tell you the excate procedure at all but i do know that 134a takes a long time to get every cold as to r 12 plus you need to make sure all the r 12 oil is out of your system before filling back up with 134 A or the system will be contamenated

When you retro fit the A/C system from R12 to R134 the system will not cool as much as it used to because R12 just cools better. You're actually better off keeping the R12 in the A/C system, even though it's harder to find and more expensive than R134.

Try pulling to down for about twenty minutes... another factor that will help is installing an electric fan in front of the condenser so it will push air over the coils while you're stopped.

Vehicles designed for R12 have smaller evaporators than those designed for R134a, therefore the a/c cooling capacity will be diminished in a conversion. Tint your windows as that will help.
