3. Turn the tensioner clockwise by using an Allen wrench.





4. Disconnect the tensioner spring from the hook pin.

Caution: Forcefully twisting the belt, turning it inside out, or allowing oil or grease on it will damage the belt and shorten its life.





Note: Mark the timing belt rotation on the belt for proper reinstallation.

Tensioner, Tensioner Spring Installation Note





1. Measure the tensioner spring free length. If not within the specification, replace the tensioner spring.
Free length: 36.6 mm (1.44 inch)
2. Install the tensioner.





3. Rotate the tensioner. If tensioner rotates with no resistance or does not rotate, replace the tensioner.

Caution: Be sure not to apply tension other than that of the tensioner spring.

5. Turn the tensioner clockwise by using an Allen wrench.





6. Connect the tensioner to the hook pin.





7. Turn the crankshaft clockwise twice, and verify that all timing marks are aligned. If not aligned, repeat from Step 1.
