  Q: How to replace the evaporator core on GMC Safari?

  A:

  Start by preparing the required tools which must include the j 39400-a as your first step before commencing work. The air cleaner should be removed followed by refrigerant recovery from the system. At the next step disconnect both electrical connectors and take away the coolant recovery reservoir. Proceed to remove the compressor hose assembly from the accumulator before taking out the bypass valve bracket from the outer case. Disconnect the Evaporator tube from both the accumulator and relay bracket followed by its complete removal from the Evaporator. Unscrew the screws installed in the outer Evaporator case to detach this outer component from its module position. To split the Evaporator module evenly separate all screws before extracting first the inner case and second the Evaporator core. Begin the installation of new Evaporator core by properly placing it into position but always refer to fastener specifications. The inner case should be reattached to the Evaporator module with screws tightened to 6 n.m (53 lb in). Afterward install the outer case and tighten its screws to the same specification. Firstly insert the Evaporator tube to the Evaporator while the second step includes attaching the bypass valve bracket to the outer case. Place the Evaporator inside the accumulator before installing both the compressor hose assembly at the accumulator location and the relay bracket. Install electrical connectors before you put in the coolant recovery reservoir then refill engine coolant then proceed with evacuating the system before charging it before removing the air cleaner.

  Q: How to service and repair the auxiliary evaporator core on GMC Safari?

  A:

  Service and repair operations for the auxiliary evaporator core should start with a systematic refrigerant recovery procedure of the system. Rephrase the sentence by starting with the removal of the left body side rear trim panel and air outlet duct assembly and proceeding to disconnect electrical connectors. Support the vehicle with tools and remove the retaining nut to break free the auxiliary evaporator rear tube assembly from its core position. First secure the auxiliary evaporator module assembly by taking out the mounting bolts. Afterward remove the vehicle case from its mounting position. You must take out all the screws from the case to gain access to its evaporator core seal and the core for removal. Check the gaskets and seals for any signs of damage before performing required replacements. Before assembling the case parts place the evaporator core inside and then apply the evaporator core seal before reinstallation. Fasten the auxiliary evaporator module assembly on the vehicle while tightening bolts to 10 N.m (86 lb in). When the vehicle reaches the proper height support it while attaching the auxiliary evaporator underbody rear tube assembly to the core using a retaining nut which should be tightened to 10 N.m (86 lb in). After the electrical connection reinstallation, replace the air outlet duct assembly together with the left body side rear trim panel. After the system evacuation and recharge process the Halogen Leak Detector (J 39400-A) will test all component fittings for leaks.
