BENDIX AD-RP AIR DRYER REMOVAL
1. Park the vehicle on a level surface and prevent
movement by means other than the brakes.
2. Drain ALL reservoirs to 0 psi (0 kPa) Caution: The
compressor discharge line may still contain
residual pressure.
3. Identify, mark and disconnect the supply, delivery,
control, and remote purge port air lines. Disconnect
the wiring harness connector from the heater and
thermostat assembly connector on the body assembly.
4. If so equipped, disconnect, remove and save the
exhaust line from the exhaust port of the air dryer.
5. Remove the three mounting bolts that secure the air
dryer to the vehicle and remove the air dryer.

since their length is specifi c to mounting the air dryer
