52. Timing Belt Installation

1. Ensure that the mark on the camshaft timing belt pulley is aligned with the V mark on the inside of the timing belt cover. If not, align the two marks by turning the camshaft.





2. Ensure that the punch mark on the crankshaft timing belt pulley (2) is aligned with the arrow mark on the oil pump case (1). If not, align the two marks by turning the crankshaft. Do not turn the crankshaft more than its allowable turning range.

Important:
^ Match the arrow mark on the timing belt with the rotating direction of the crankshaft, when installing the timing belt.
^ Ensure that the No. 1 piston is at top dead center of the compression stroke.





3. Align the timing marks.
4. Push the tensioner plate (1) up.
5. Install the timing belt.
6. install the tensioner spring and the spring damper. Ensure that there is no slack in the timing belt.
7. Install the tensioner stud only.
8. Turn the crankshaft two rotations clockwise after installing the timing belt. This will take up the slack in the timing belt.

Notice: Refer to Fastener Notice in Service Precautions.

9. Tighten the timing belt tensioner stud.
Tighten the timing belt tensioner stud to 11 Nm (97 inch lbs.).
10. Secure the timing belt tensioner bolt.
Tighten the timing belt tensioner bolt to 27 Nm (20 ft. lbs.).





11. Confirm again that both sets of timing marks (1,4) and (2,3) are aligned properly.

Important: Ensure that the coolant pump-to-oil case seals and the coolant pump-to-cylinder head seals are in place before you install the timing belt cover.





12. Install the timing belt cover (10). Secure the timing belt cover with the eight bolts and the one nut.
Tighten the timing belt cover nut and bolts to 11 Nm (97 inch lbs.).
