Timing Chain Replacement

REMOVAL
1. Disconnect battery negative cable.
2. Drain cooling system.
3. Remove timing chain cover.

Alignment Of Timing Marks:

4. Rotate crankshaft to align timing marks to #1 TDC.
5. Remove camshaft sprocket attaching bolt and remove timing chain with crankshaft and camshaft sprockets.

Compressing Tensioner For Chain Installation:

6. Slip crankshaft sprocket onto crankshaft and compress tensioner shoe by placing a large screwdriver between crankshaft sprocket and tensioner shoe. Compress shoe until hole in shoe lines up with hole in bracket. Slide a suitable pin into the holes and remove screwdriver.
7. If tensioner assembly is to be replaced, remove the three tensioner to block bolts and remove tensioner assembly.

INSTALLATION
1. If tensioner assembly is being replaced, install tensioner and mounting bolts. Torque bolts to 24 Nm (210 inch lbs.).
2. Place both camshaft sprocket and crankshaft sprocket on the bench with timing marks on an exact imaginary center line through both camshaft and crankshaft bores.
3. Place timing chain around both sprockets.
4. Lift sprockets and chain (keep sprockets tight against the chain in position as described).
5. Slide both sprockets evenly over their respective shafts and verify alignment of timing marks with a straight-edge if necessary.
6. Install the camshaft bolt. Tighten the bolt to 68 Nm (50 ft. lbs.) torque.
7. Remove tensioner pin. Again, verify alignment of timing marks.
8. Install timing cover.
9. Fill cooling system.
