Air Conditioning

Just installed A/C in my F150. Came out of an '87, I have a '94. I replaced the o-rings, and charged it up with 30 oz of 134 and oil. Anyone know if I should go for 20# 30#, 40# on the low side?

Thread moved to " Cooling, Heating, Ventilation and A/C" tech forum. There should be more resources here to help with your question.

sorry, thanks. I didn't know how to move it, so I reposted when I figured out there was a better place. Thanks for not yelling at me

your low side pressure will vary with the following
RPM
outside temp
engine temp
max or norm setting
blower fan speed
fan clutch condition
presence of (non condensable gasses)air How long did you pull vacuum?
The 1987 system had a poor condenser design (for 134a) 94-96 condensers work much better
How cold is it getting? and at what setting?
