3. Open the top and bottom stopcocks by turning them parallel to the nozzle and permit water to
drain from the radiator. Then close the stopcocks and remove the drain hose from the bottom
stopcock.
Note: A small amount of water/antifreeze mixture may remain in the tubing
leading from the external connector to the reservoir. This can be drained by
pulling the hose off of the ribbed section of the quick-connect fitting previously
installed. Reattach the tubing before completing the remainder of this
procedure.
4. Replace the external housing on the Air/Water Heat Exchanger and secure it with the six screws
previously removed. If necessary, reseat the gasket around the reservoir opening with a small
screwdriver.
5. Add water/antifreeze mixture to the Exchanger per the instructions in the section Fill the
Air/Water Heat Exchanger to complete the water/antifreeze flush and drain procedure.
