2002 Ford E-250 Econoline A/C Expansion Valve Parts Questions & Experts Answers

• Q: How to Service and Repair the A/C Expansion Valve in the Auxiliary Climate Control System on 2002 Ford E-250 Econoline?

  A: The first procedure for supporting the expansion valve in the auxiliary climate control system requires the removal of the A/C evaporator core assembly. Rigorously detach the capillary bulb from the outer evaporator outlet tube yet protect both items from harm. The technician should first detach the clip securing the capillary bulb along with the A/C insulating tape from the tube. The service requires disconnecting all refrigerant lines by using a wrench on each fitting so the components stay undamaged throughout the procedure. To install an A/C evaporator expansion valve you must position the new green O-ring seal which receives PAG Refrigerant Compressor Oil (R-134a Systems) or similar lubrication in the connections. Reinstall the A/C evaporator expansion valve before properly connecting both the A/C liquid jumper line and inlet line to each other. Use clips to fasten the evaporator outlet tube capillary bulb while wrapping A/C insulating tape around the bulb along with the tube. The final step is to reinstall the A/C evaporator core followed by system evacuation then charging while conducting a correct operation check.
