Want this question answered?
I have 1998 chev suburban with rear air do they use two orifice tubes
Most orifice tubes are placed in the high pressure line to the evaporator at the fire wall connection. You will have to empty the freon from the system to replace the orifice tube which is not very expensive (the tube, that is).
where is the orifice tube location on a 1996 GMC pickup truck 1500
location of orfice tube in a 1999 chevy malibu On your 1999 Malibu the expansion (orifice) tube is located at the condenser to evaporator connection in the evaporator tube.
You can find a diagram of the location by clicking on the link below. Follow the icon for "Find your low side port." It will be #9 "Condenser to evaporator tube."
On some suburbans its at the connection behind passenger turn signal.
Located in front of the radiator on the passenger side in the condensor line.
If it has a rear orifice it's in the rear unit under the roof panel.
It's located on the left side fender well right before you get to the battery, look down and you will see a a/c line disconnect that line and it will be inside, you will needle nose pliers to pull the orifice tube out. >>> (your a/c system has to free of all pressure before you disconnect that line!!!!!)
It is located in the liquid line or tube between the condenser and evaporator.
How do you change the orifice tube on 1997 grand Cherokee jeep with 5.2 v/8
Yes it does; but I'm not sure of the location. They can be difficult to find.
