Default AC low side pressure
Anyone know what the correct AC low side pressure should be on the factory AC?

From what I've read I've seen 35-45 psi -

i know in ac systems for your house we like to see between 60-75psi and around 225+ on the high side. Not to sure if they are similar.

With out the compressor running it reads 110 on the low side - The system must have equaled out.... I'm putting gauges on in the AM to see what it is reads highs and low while running...

y are you putting guages on it anyway? Every time you put guages on you release a little refridgerant thus messing up the factory charge. We never put guages on a system unless it is absolutly neccisary

Yeah - I figured I'd have to re-add more refridgerant - but I suspect it's a little low - I plan to add what I need to make the pressure correct - assuming there'no issues (fingers crossed)

The low side pressure is going to depend on the cabin temp with the system on recirc., fan speed and engine rpm. around 35 will be close. but as mentioned, it will vary depending on above conditions.
