4. Lift the engine slightly using the jack to obtain space for releasing the timing chain tensioner.

1. Insert a pick into the service hole in the timing chain cover and lower the hole in the left side of the ratchet plate (A) on the tensioner to allow the pawl (B: located inside the tensioner behind the ratchet plate) to be lifted.

3. With the tensioner plunger in the fully retracted position, raise the hole in the left side of the ratchet plate (A) again through the service hole in the chain cover to align the ratchet plate hole with the hole in the tensioner body behind the ratchet plate, then lock the tensioner by inserting the pick through the ratchet plate and tensioner body holes.
