Where's the Orifice Tube?

vhausauer on Fri July 24, 2009 12:18 AM User is offline

Year: 1995
Make: Chevy
Model: Suburban
Engine Size: 350
Refrigerant Type: 134

Hate to sound like a complete idiot, but I was hoping this info would be in the book. Where did Chevy put the orifice tube in this darn truck?

If this truck has rear air it will be in a connection just below the battery. If it does not have rear air the tube should be behind the passenger side turn signal.

Guessing I gotta tear under my dash to find it. Probably in the evaperator?

Thanx. Man I feel dumb right about now.

ou can get it out by just removing the turn signal lense--no need to pull the grille---just takes some creativity.....it is a backwards condenser out (black) style OT

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
