Toyota AC pressure and vent temp

Sixseas on Sat July 10, 2010 2:46 PM User is offline

Year: 2000
Make: Toyota
Model: Echo
Engine Size: 1.5L
Refrigerant Type: R134a
Ambient Temp: 80
Country of Origin: United States

Hi, I have a 2000 ECHO and will likely run it across the Mojave next month and want to make sure shes working at full capacity.
Does anybody have the AC test procedure, vent temps and High and Low pressure by ambient temperature? Also if you can refresh my memory on using the site glass, it foams a bit when the compressor clicks on but is otherwise clear. I asked the local dealer they had no idea or wouldn't tell me. Thanks
