Evaporator Core

Performing a leak test should be the first step when servicing the evaporator core unless its removal from the vehicle is necessary. A new receiver/drier cartridge needs to be installed only when physical signs of contamination arise due to an A/C compressor failure or damage to the existing cartridge. Start by taking out the heater core along with evaporator core housing followed by unscrewing the wire harness from the housing. The evaporator core cover needs twenty-five screws removed which will separate the housing into its two component parts. You must pull out the dash panel seal followed by removing the evaporator core. Follow the reverse order of removal to install the new core by applying the right amount of clean PAG oil to the refrigerant system.

The service of evaporator core starts with leak testing whenever there is an indicator of leakage before removing the core. Efforts should start by detaching the wire harness from the housing and then extracting both the heater core and evaporator core housing. The evaporator core needs its cover secured by 15 screws until both housing halves can be divided. The first step should involve removing the dash panel seal followed by the evaporator core extraction. Both steps for assembly follow the removal procedure but include addition of the proper quantity of clean PAG oil throughout the refrigerant system.

Service of the evaporator core begins by testing for leaks when removal is necessary. The installation of a new A/C desiccant cartridge requires only when contamination comes from failed A/C compressors or when the existing cartridge shows signs of damage. Start the process by removing both heater core and evaporator core housing followed by wire harness detachment from the housing. The evaporator core cover requires removal of its 15 screws before separating the housing into two sections. Pull out the dash panel seal before extracting the evaporator core. During the installation process first undo the removal steps while adding clean PAG oil in the correct amount to the refrigerant system.
