1. Remove the return hose from the P/S reservoir and plug the reservoir from the place that you removed the hose from.
2. Insert the return hose into a catch container.
3. Start the engine and fill the reservoir with new fluid.
4. The old fluid will flow through the return hose into the catch container while you are pouring new fluid into the reservoir.
5. After enough new fluid has cycled through the system, stop the engine.
6. Reconnect the return hose to the reservoir. That’s it.
