How to replace the A/C Orifice Tube and accumulator-drier in an air conditioning system on Ford Explorer?

Whenever the A/C Orifice Tube is replaced, the accumulator-drier should also be replaced. Removal of the A/C Orifice Tube involves having the air conditioning system discharged and the refrigerant recovered. Disconnect the cable from the negative terminal of the battery. Disconnect the condenser-to-evaporator refrigerant line at the firewall. The A/C Orifice Tube is a tube with a fixed-diameter orifice and a mesh filter at each end. When you separate the pipe at the fitting you will see one end of the A/C Orifice Tube inside the pipe leading to the evaporator. Use a special removal tool to remove the A/C Orifice Tube. The A/C Orifice Tube acts to meter the refrigerant, changing it from high-pressure liquid to low-pressure gas. It is possible to reuse the A/C Orifice Tube if the screens aren't plugged with grit or foreign material, neither screen is torn, the plastic housing over the screens is intact, and the brass orifice inside the plastic housing is unrestricted. Installation is the reverse of removal. Be sure to insert the A/C Orifice Tube with the shorter end in first, toward the evaporator, and lubricate the refrigerant line and the A/C Orifice Tube with clean refrigerant oil to aid assembly. Retighten the fitting and refrigerant line, then have the system evacuated, recharged and leak-tested by the shop that discharged it.

Ford Explorer A/C Orifice Tube

The A/C Orifice Tube of the Ford Explorer meters liquid refrigerant so that the inside of the cabin remains cool while also preventing pressure extremes between the system's high and low sides. In contrast to an adjustable expansion valve, which varies the size of its opening in response to temperature feedback, the fixed screen tube uses a calibrated bore and mesh to regulate flow, prompting the compressor to cycle on or off to match demand. Understanding how the A/C Orifice Tube works is very important since every late model Ford Explorer depends on the A/C Orifice Tube instead of a thermal valve. Over time, Ford's use of a single metering concept on most Explorers has had only minor tweaks in bore size and filter density, but the one-piece insert also traps dirt before it gets to the evaporator. Clogs in the A/C Orifice Tube may cause cooling loss at idle, erratic pressures, or even an evaporator freeze. Timely cleaning or replacement of the A/C Orifice Tube restores steady performance while the Ford Explorer makes any ride enjoyable.
