Timing Belt Tensioner
1. Install the timing belt tensioner and tensioner
spring.
2. Tentatively secure the tensioner with the spring fully
extended.
Timing Belt
1. Install the timing belt so that there is no looseness
at the tension side, and at the two camshaft pulleys.
Caution
a) If the timing belt is being reused, it must be
reinstalled to rotate in the original direction.
b) Check that there is no oil, grease, or dirt on
the timing belt.
2. Loosen the tensioner lock bolt.
