NOTE: When installation is complete, the tangs
of the two hose clamps should face
outward, away from the flywheel and
slightly down. See Figure 11-52.

9. Push down on the formed tube and hold in this
position to prevent it from pivoting upward
when tightening the hex cap. Torque the hex cap
to 22.6 N·m (200 in. lb.), to secure the joint
connection. Support the fitting with a wrench
while torquing, if possible, to prevent applying
unnecessary pressure on fitting and joint. See
Figure 11-53. Check that the formed tube and
hose section have not been pulled up.

10. Install the drive belt onto the cogged pulley of
water pump, then around the cam pulley. Slide
the cam pulley, with the belt attached, down
onto the keyway end of the camshaft. Be careful
not to push the key out of the keyway and/or into
the seal when installing the pulley. See Figure
11-54.

11. Check or use a feeler gauge to see that there is at
least 3.17 mm (0.125 in.) clearance between the
underside of the pulley, and the hose, tube, and
clamps. Remove the pulley and reposition the
tube or clamps if required. Install the flat washer
and hex flange screw, to secure the pulley in
place. Torque the screw to 9.9 N·m (88 in. lb.). See
Figure 11-55.
