If a leak occurs between the tubing and the tube nut, replace the hose assembly.
If a leak occurs between the tube nut and the pump outlet replace the plastic
washer.
- Check the fitting to determine whether the leak is between the tube and
tube nut or between the tube nut and pump outlet.
- If the leak is between the tube nut and pump outlet check to be sure the
nut is tightened to 30–40 ft. lbs. Do not overtighten this nut.
- If the leak continues or if the leak is between the tube and tube nut, remove
the line.
- Unscrew the tube nut and inspect the plastic seal washer. Replace the plastic
seal washer when the line is removed.
- To aid in the assembly of the new plastic seal washer, a tapered shaft may
be required to stretch the washer so that it may be slipped over the tube
nut threads.
- If the rubber O-ring is damaged it cannot be serviced and the hose assembly
will have to be replaced.
- Connect the tube nut and torque to 30–40 ft. lbs.
CAUTION
The quick connect fitting may disengage if not fully assembled, if the snapring
is missing or if the tube nut or hose end is not machined properly. If the
fitting disengages replace the hose assembly. The fitting is fully engaged
when the hose will not pull out. To test for positive engagement the system
should be properly filled, the engine started and the steering wheel turned
from stop to stop.
