If you can get a portable temperature measuring tool, often used in food cooking, and stick it in the vent then you will get anywhere from 42-45 DegF on the vent exit with a full charge. Be careful not to introduce air when you are connecting to the system as the air will royally screw things up
good luck

My AC condenser was punctured and let out a stream of the R134a. I've popped in a new condenser and assumed the system is completely empty so I've pumped a can into it so far (18oz). Pelican also mentioned the 30oz the car would take so I guess I'll try and get another 12oz in there. Thanks
