how to make R134 work as well as R12.
sixto - you have been around long enough to know what Larry is going to tell him
Jacob - do a search on this site. You will regret going to 134 in Houston on one of these cars
. I live in a similar climate and I have converted two BACK to r12 and have been very happy with the reverse conversion. One of them is on a black 300D. I have seen the inside temp indicator be at around 125dF in August and the r12 does a good job of getting it comfortable in a fairly timely manner.
