The orifice tube is a plastic tube with a filter inside, and it is part of the air conditioning system. On some models, it is located in the high-pressure line from the condenser, while on other models, it's located in the evaporator inlet line.

To remove the orifice tube, a small tool is needed to be inserted and expanded until it grabs the orifice tube, allowing it to be pulled out. The same tool can be used to insert a new orifice tube. It's important to make sure the tube is inserted in the same direction as the old one.

Replace the orifice tube and have the system evacuated, recharged, and leak tested by the shop that discharged it.

Drain and measure the refrigerant oil from the compressor. If the compressor is being replaced, add the appropriate amount of refrigerant oil to maintain the correct level.

If the amount of oil removed was between three and five ounces, add the same amount of clean refrigerant oil to the new compressor. If the amount of oil removed was greater than five ounces, add only five ounces to the component before installation. If the amount of oil removed was less than three ounces, add three ounces to the component before reinstallation.
