2007 GMC Envoy A/C Orifice Tube Parts and Q&A

• Q: How to replace the A/C Orifice Tube on a short wheelbase on 2007 GMC Envoy?

  A: You need to begin A/C Orifice Tube replacement on short wheelbase vehicles by recovering coolant then taking out the accumulator. The first task involves disconnecting the evaporator tube nut from the evaporator while you pull away the evaporator tube. After discarding the o-ring seal you must remove the evaporator tube block fitting nut and open the evaporator tubes (4,6) at this fitting. The A/C Orifice Tube remover (J26549-E) helps professionals properly extract the A/C Orifice Tube out of the evaporator tube. The shorter screen end of the A/C Orifice Tube needs to enter the evaporator tube first during installation while using a tool called the A/C Orifice Tube remover (J26549-E). Use a new o-ring while reassembling evaporator tubes (4,6), torquing the evaporator tube nut to 28 n.m (21 lb ft). Lightly attach the evaporator tube to its fitting component using a nut that requires the proper torque amount. The process ends with Coolant Reservoir and accumulator reinstallation and refrigerant system recharging followed by checking fittings with the halogen leak detector (J39400-A).
