11. When testing is complete, connect the Drain Hose to the Shuttle
Valve using the quick-connect. Make sure the quick-connect
sleeve snaps forward to lock the connection (Fig. 32).
12. Place the opposite end of the Drain Hose into a container
appropriate to capture hot, pressurized coolant. Use the
Hose Clip to secure the Drain Hose in position (Fig. 33).
13. Shift the shuttle valve to the the "Open" position, allowing the
hot fluid and pressure to be expelled (Fig. 34).
14. Once all pressure is relieved, cautiously disconnect components,
clean and store them properly.
Caution: Hot fluid being expelled through the test equipment will
cause quick-connects and other metal components to become
hot. Handle such components with care, using a rag if necessary.
15. Refill the radiator or coolant bottle to the proper level, and
replace the cap.
