REMOVAL AND INSTALLATION (Continued)
(10) Install the power steering pump and bracket
assembly to the water pump and intake manifold.
Hand start the three (3) tensioner bracket to p/s
pump to intake manifold bolts and the two (2) ten-
sioner bracket to water pump bolts.
(11) Tighten the power steering pump bolts to 28
N·m (21 ft. lbs.) Tighten the tensioner bracket to
water pump bolts to 28 N·m (21 ft. lbs.).
(12) Connect the accelerator cable, cruise control
cable (if equipped), and the transmission line pres-
sure cable (if equipped) to the hold-down bracket and
the throttle lever.
(13) Install and tension the accessory drive belt.
Refer to Group 7, Cooling System for the proper pro-
cedure.
CAUTION: Ensure that the accessory drive belt is
routed correctly. Failure to do so can cause the
water pump to turn in the opposite direction result-
ing in engine overheating. Refer to Group 7, Cool-
ing System for the proper procedure.
