Initial Fill

1. Install the cap on the power steering pump fill neck or rubber stopper on power steering oil reservoir.
2. Open valve No. 1 and allow the power steering fluid to bleed through the tee fitting. Close valve No. 1 after bleeding.
3. Pour enough steering fluid in the power steering pump reservoir to exceed the amount required for filling the system.
4. Close all valves.
5. Open valves No. 2 and No.3 Start the vacuum pump. Operate the pump until a gauge reading of 84-101 kPa (25-30 inch-Hg) is obtained.
6. Close valve No. 3 and shut off the vacuum pump. Watch the gauge for approximately 30 seconds. If the vacuum reading drops more than 3 kPa (1 inch-Hg) there is a leak in the power steering or filling system that must be corrected.
7. Start the vacuum pump. Open valve No. 3.Operate the pump until a gauge reading of 84-101 kPa (25-30 inch-Hg) is obtained.
8. Close valve No. 2 and shut off the pump. Open valve No. 1 to fill the steering system with Motorcraft MERCON Multi-Purpose (ATF) Transmission Fluid XT-2-QDX or equivalent meeting Ford MERCON specification. The power steering pump reservoir should be elevated higher than the power steering pump and power steering oil reservoir.
9. When fluid stops draining from power steering pump reservoir, close valve No. 1 and remove cap or rubber stopper.
