12. MAINTENANCE
The power steering system requires little
maintenance. However, the system should be
kept clean to ensure maximum operating
performance and troublefree service. Periodic
inspections should also be made to check for
leakage and all parts for damage or distortion.
Insure all fasteners are tight (see "14.
Specifications" for recommended tightening
torques.
When the slightest evidence of dirt, sludge or
water is discovered in the system, disconnect fluid
lines at the power steering gear to drain the
system. Drain and refill the system with "Dexron-
IIE or Dexron-III" automatic transmission oil.
