Tools Required:
- Teflon Seal Installer D90P-3517-A3

Seal Replacement

Note:
- If a leak occurs between the tubing and tube nut, replace the power steering pressure hose/ power steering return hose assembly.
- If a leak occurs between the tube nut and the pump outlet, replace the plastic washer.
- The following procedure should be used:






1. Check fitting to determine whether leak is between tube and tube nut or between tube nut and power steering pump outlet.
2. If leak is between tube nut and power steering pump outlet, check to ensure nut is tightened to 27-34 Nm (20-25 ft-lbs.).

CAUTION: DO NOT OVER-TIGHTEN. IF TUBE NUTS ARE OVERTORQUED, STRIPPING OF HOUSING THREADS MAY OCCUR AND BORES MAY CONCAVE.

3. If leak continues or if leak is between tube and tube nut, remove power steering pressure hose/ power steering return hose.

Special Tool D90P-3517-A3:

4. Unscrew tube nut, and inspect plastic seal washer.
Always replace plastic seal washer (388898-S) when power steering pressure hose/ power steering return hose is removed.
To facilitate assembly of new plastic seal washer, a tapered shaft may be required to stretch washer, so it may be slipped over tube nut threads.
5. The rubber o-ring (3Z728) cannot be serviced with this design.
If leak is due to the o-ring replace the power steering pressure hose/ power steering return hose assembly.
6. Connect tube nut and tighten to 27-34 Nm (20-25 ft-lbs.).

Note:
- The quick connect fitting may disengage if not fully assembled, if the snap ring is missing, or if the tube nut or the hose end is not machined properly.
- If the fitting disengages, replace the power steering pressure hose/ power steering return hose assembly. The fitting is fully engaged only when the power steering pressure hose/ power steering return hose will not pull out. To test for positive engagement, the system should be properly filled, the engine started, and the steering wheel cycled from lock-to-lock. Service power steering pressure hose/ power steering return hose assemblies have tube nuts, snap rings and o-rings already connected.
