So my a/c wasn't as cold as it was so I put a recharge can into it and not it blows out hot air then about 10 mins of driving it gets a little cooler. Did I put to much in? Anyone know the psi it's to be at
between 25 and 45psi. On an older system though, you really dont want to be hovering around the 45psi mark when recharging.
Its gon a depend on type of gas you have,supposing you got R125 would be between 35_45 PS I depending on outside temp.
Maybe you got air in the line,
Ended up to be that my cooling fan took a crap as I was doing it
40 is the sweet spot to charge on while the a/c is running... I however do not charge with do it yourself cans.. at the very least a set of manifold gauges.. a machine is best though. and for josean's comment... the average person can't buy R-12.. you have to be ASE certified to buy it. 3rd gen J's are 134-A anyway, not sure when they switched the systems over on j's...

PRESSURE is not how you measure a proper A/C charge.

It is part of the process though. Like i said i don't charge with do it yourself cans, usually a machine or at the least manifold gauges. Monitoring the pressure while the system is running is the only way to do it when you don't know how much is in it without recovering everything and starting over. Too much refrigerant in the system and the high pressure switch will activate, too little and the low pressure switch will give fits. Pressure is a big part of it.
