Receiver Dryer: Testing and Inspection

RECEIVER/DRIER
1. Check the fusible plug and 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 temperature. If difference in temperatures between the inlet and outlet is large, replace the receiver-drier.

NOTE
1. Plug all open fittings immediately to keep moisture out of the system.
2. Do not remove the blind plugs until ready for connection.
3. If the receiver-drier is replaced with a new unit, add 40 cc of compressor oil to the compressor.
4. Evacuate, charge and test the refrigeration system.
