Frontier 4WD V6-3.3L (VG33E) (2003)
5. Push the middle of the timing belt between the RH camshaft sprocket and tensioner pulley with the specified force [98 N (10 kg, 22 lbs.)] to apply
tension on part "A".and part "B" of the timing belt as shown.
6. Loosen the tensioner lock nut, keeping the tensioner steady with a hexagon wrench.
7. Position a feeler gauge size 0.5 mm (0.0206 inch) thick and 12.7 mm (0.500 inch) wide under the tensioner pulley as shown.
8. Turn the crankshaft clockwise until the feeler gauge is positioned between the tensioner pulley and the timing belt as shown.
^
The timing belt will move about 2.5 teeth.
9. Tighten the tensioner lock nut, keeping the tensioner steady with a hexagon wrench.
10. Turn the crankshaft clockwise or counterclockwise to remove the feeler gauge.
11. Turn the crankshaft clockwise at least two full rotations, then slowly set the No. 1 piston at TDC on the compression stroke.
12. Measure the deflection of the timing belt midway between the camshaft sprockets while pushing with a force of 98 N (10 kg, 22 lbs.) as shown.
Belt deflection when engine is cold (reference value): 13 -15 mm (0.51 - 0.59 inch) at 98 N (10 kg, 22 lbs.) force
13. If the belt deflection is not within specification, return to step 1 and repeat procedure.
