6. Install the timing chain over the exhaust camshaft sprocket, around the idler sprocket and around the crankshaft sprocket.
7. Set the camshaft sprockets at the timed position and use the following procedure in order to install the timing chain:
a. Remove the alignment dowel pin from the intake camshaft.
b. Use the camshaft sprocket wrench in order to rotate the intake camshaft sprocket counter clockwise enough to slide the timing chain over the
intake camshaft sprocket.
c. Release the camshaft sprocket wrench. The length of the chain between the two camshaft sprockets will tighten.
d. If properly timed the intake camshaft alignment dowel pin should slide in easily. If the dowel pin does not fully index, the camshafts are not
timed correctly and the procedure must be repeated.
8. Leave the alignment dowel pins installed.
9. Raise and support the vehicle.
10. With the slack removed from the chain between the intake camshaft sprocket and the crankshaft sprocket, the timing marks on the crankshaft and
the cylinder block should be aligned. If the marks are not aligned, move the chain one tooth forward or rearward, remove the slack and the recheck
marks.
11. In order to reload the timing chain tensioner assembly to its zero position, form a keeper from a piece of heavy gauge wire.
12. Apply a slight force on the tensioner blade in order to compress the plunger.
13. Insert a small screwdriver into the reset access hole, and pry the ratchet pawl away from the ratchet teeth while forcing the plunger completely in
the hole.
14. Install the keeper between the access hole and the blade.
15. Install the tensioner assembly to the chain housing. Recheck the plunger assembly installation, it is correctly installed when the long end is toward
the crankshaft.
16. Install the timing chain tensioner bolts. Tighten the bolts to 10 Nm ( 89 lb in ).
17. Lower the vehicle enough to reach and remove the alignment dowel pins.
18. Rotate the crankshaft clockwise (normal rotation) two full rotations.
19. Align the crankshaft keyway with the mark on the cylinder block and reinstall alignment dowel pins.
20. Alignment dowel pins will slide in easily if the engine is timed correctly.
