DESCRIPTION
The following information is designed to assist dealers in determining when to replace the receiver-drier when replacing other A/C components. Do not replace the receiver-drier unless the following criteria has been met.
RECEIVER-DRIER REPLACEMENT CRITERIA WHEN REPLACING OTHER A/C SYSTEM COMPONENTS:
Replace the receiver-drier when the A/C system has been ruptured and ALL system pressure is lost.
Receiver-drier will require replacement if the compressor oil becomes discolored or foreign substances become visible as indicated in the flow chart.
If an A/C component has failed, extract the compressor oil from the failed part and inspect the oil according to the procedure. Follow the procedure to determine if the receiver-drier requires replacement as a precaution.
CAUTION:
Before charging, always evacuate the A/C system thoroughly to remove air and moisture. Use a vacuum pump to evacuate the system. Hold vacuum at 29 inches (740 mm Hg) for 5 - 10 minutes
