INSTALLATION

NOTE: Be certain to add refrigerant oil if the rear receiver/drier is being replaced. The refrigerant oil must be drained from the old receiver/drier and measured to determine the amount of refrigerant oil to add to the new receiver/drier. Use only refrigerant oil of the type recommended for the rear A/C compressor in the vehicle.

1. If the rear receiver/drier is being replaced, install the correct amount and type of refrigerant oil into the new rear receiver/drier. Drain the old receiver/drier and measure the refrigerant oil. Fill the new receiver/drier with the same amount of new refrigerant oil that was drained out of the old receiver/drier.

NOTE: The rear receiver/drier is labeled with a direction-of-flow arrow to indicate refrigerant flow through the receiver/drier. Make sure to properly install the rear receiver/drier in the correct direction.
