ACTION REQUIRED

Replace the evaporator coil using Disassembly and Assembly, D8T Track-Type Tractor Machine Systems, "Refrigerant Evaporator Core and Heater Core - Remove and Install".

Be sure to use a wrench to hold the evaporator coil fittings on the new coil in place so it does not twist and crack at installation.
