Remove the washer and overflow bottle. The high side service port is on a pipe about eight inches long to make it easier for service. The fitting and orifice tube are near this pipe. The fitting is covered with a protective rubber cover that makes it hard to see the fitting.
Push the cover back.
Disconnect the fitting.
Replace the orifice tube.
Lubricate the new o-ring and torque the fitting to 18 foot pounds.
Ford says to use a special too to get the orifice tube out of the hose. I find needle nose pliers gets the job done real well unless it is really stuck then use the tool.
If you have any comments please feel free to leave them here.
There is one orifice tube for the font air. It is located in the a/c line coming from the condenser to the evap. core. the rear a/c has and expansion valve attached to the rear evap. core. Hope this helps.
I believe the orifice tube on this model requires the a/c pipe to be cut to install a new tube. You need to discharge the system, replace the tube, then evacuate miosture with a vacuum pump, then recharge with R134A refirgerant. Not a job for a non technical person.
The oriifce is in the line just before the evaporator that is in your car a/c heater case. It is where the liquid refrigerant turns into a vapor as it comes out of the orifice and then it absorbs heat from the air going into you car, thus blowing cold air. Moisutre in the warm air condenses and as he iar gets cold and it drains out of your evaporator and out the drain & onto the ground
