Engine and tranny are out of the car, and while everything is out I decided to overhaul my A/C system. Pulled the orifice tube today, you can see the attached picture, it looked pretty gunked up. I do have a 1998, but the orifice tube was NOT located up near the condenser. The orifice tube was under the brake booster as it is in the 99+, but it is still the 97-98 type orifice tube, and it was located inside what seems to be some type of "collector" pipe. Attached pictures I hope illustrate what I'm saying.
Anyways, I want to overhaul the system, does anyone have a list of part #'s and pieces I should replace while everything is out? O-rings? etc, etc...
Here is a partial list:
Orifice tube ac delco # 155754
Compressor ac delco # 1521662A
A/C condenser ac delco # 156961
a/c drier ac delco # 1510076
a/c refrigerant line ac delco # 1532582
If anyone has any other items I should replace while overhauling the system, I appreciate the info / advice.
