Timing Chain





Install the timing chain tensioner (232) and bolts (231).
Tighten the timing chain tensioner bolts to 25 N.m (18 lb ft).





Important:
^ The sprocket teeth and timing chain must mesh.

^ The camshaft and the crankshaft sprocket alignment marks MUST be aligned properly.

Install the camshaft sprocket (205), timing chain (208), and bolt (206).





Inspect the sprockets for proper alignment. The mark on the camshaft sprocket (1) should be located in the 6 o'clock position and the mark on the crankshaft sprocket (2) should be located in the 12 o'clock position.
