location of a/c orifice tube

[golddestiny357]

can u guys help me out to find the location of the a/c orifice tube on a 2001 pontiac montana single a/c?

There is no orifice tube. It's a TXV(thermal expansion valve) system in the 01 montana. Attached to the evaporator under the left wiper linkage. Calls for 1.8 hours labor, not including system recharge. Good luck

Interested in your ac fix ,can you describe what you did and where these components are located for future fixes ? thanks in advance.AS far as the tranny goes look at this thread

This will give you an idea on how to get at the solenoid not sure which one it is .

sure.. the expansion valve is located in the firewall on the drivers side.. to remove it u remove the bolt holding the a/c lines... after there are 2 bolts holding the expansion valve.. heres an image.. And to remove the a/c filter wich is also known as the RECEIVER DEHYDRATOR, the condenser has to be removed.. easiest way is to remove the engine supoerts on the front, remove the radiatoer suport on top then remove the 3 bolts securing ther radiator and the a/c condenser together.. disconect the condenser a/c lines, then push the radiator all the way towerds the manifold so u can get enough space to pull the condenser out.. its pulled out towerd the top.. then u just simply remove the RECEIVER DEHYDRATOR from the condenser.. heres an image... hope this helps

Thanks for your input the knowledge. What is the size of the two nuts at expansion valve? l could not measure it exactly. 19 mm or 3/4 "; 23mm or 15/16 inch on Montana2003? If flare wrench nuts can be worked? Thanks for your help!
