Just installed the R134a in the 300TD. Parallel flow condensor, 14X22.5.

All parts of AC system new. Evaporator was leaking which started all this. Had about 50% blockage of air flow on the evaporator.
Here's the link to that post

Heres the question. How much freon did your system take. Mine calls for 42 oz and the normal 80% of R134 for a R12 system should have it take 34 oz or so. It's taking about 30 oz. With that amount the vents are 35 degrees (outside 72) with the Aux fan on and an extra fan blowing on it. Did you find your setup took less?

Also. My pressures are running low. The manual calls for 22psi low and 265 high. I'm running 17 and 185. But the vents are 35 degrees. What are you running?

For everyone. I'll post the results of the parallel flow conversion with R134a as the summer progresses. I will try to set up a meeting with Larry Bible and do a side by side comparison. If the R12 is better I'll convert and we will have info on the parallel flow with R12.
