Receiver Dryer: Testing and Inspection
RECEIVER/DRIER CHECK1. Check the fusible plug and the fittings for leakage, using a leak detector.
2. Run the engine at fast idle with the air conditioning "ON", and check both the inlet and outlet temperatures. If the difference in temperatures between the inlet and outlet is large, replace the receiver-drier.
NOTE:
1. Plug the all open fittings immediately to keep moisture out of the system.
2. Do not remove plugs until ready for connection.
3. Evacuate, charge and test the refrigeration system.
