[quote="Docfixit"]Pull car into shade ambient temp 86 to 95. Close all doors place in Recirc mode fan on high. Operate engine at 1500 rpms. Pressure readings should be in this range LOW 18-28 PSI HIGH 213-242 PSI. Get the High side in that range if Low is a little higher say 30psi. That's good. Sounds like you need a touch more charge. Cutting out at 25 is in range of pressure switch let me know where it cuts out exactly.[/Quote
When filling the system do you take the bottle (30lbs) and flip it over for the freon to enter the system or do you leave it uprite and fill with the gas of the freon, My a/c tech does our motorcoachs at work and he fills the system by turning the bottle over so we are trying to make this work, but harder as it goes along.
