Some are in the inlet to the evaporator and some could be in the condenser line. You can get a new orifice tube on autozone for $5 - 20

SOURCE: How do I replace the oil dipstick tube?

The dipstick can be pulled out of the block with a pair of vicegrips and the new one driven down into the block. Before trying to pull the dipstick tube out make sure it is not held onto the block with a small bolt.

Where is the orifice tube located on a 2001 Chevy Tahoe?


Can't remember exact locations. But here is how to find it. From the compressor, follow the hose/tubing to the dryer(Big aluminium container). In the tubing you see it go from one size to a smaller size. This is where the orifice/expansion valve is. There will be a coupling to take apart. It can be two nuts to unscrew or a quick disconnect coupling. There are tools to pull it out. I just ground down a pair of needle nose pliers to pull them out. Twist it as you pull it out.

How do you install the orifice tube in a/c unit without braking it?


It will not break,unless there is something in the line already,use a round file,or a bolt,and file inside the line real good,it will take a while,there maybe residue from an old o ring from the old orifice tube,but with refridgerant oil,on the o ring of the orifice tube will help.
