2L-18 POWER STEERING GEAR AND PUMP
When adding fluid to or refilling the reservoir after
service operations, use Jeep Power Steering Fluid or
equivalent only. Use power steering fluid or fluid desig-
nated for use in power steering systems only. Do not use
transmission fluid, motor oil, or similar fluids.
The pump drive belt tension and condition should be
also be checked periodically. Use Tension Gauge J-23600
to measure belt tension. When checking tension with
this gauge, position the gauge at the center of the long-
est belt span to take readings. When checking tension of
notched drive belts, be sure the gauge finger is firmly
seated in a belt notch before taking readings.
