The cylinder head bolts are tightened in 2 progressive steps.

1. Apply a light coat of engine oil to the bolt threads and the area beneath the bolt heads that come in contact with the washers.
2. Install the bolts and plate washers to the cylinder head.
   NOTE: Do not drop the washers into the cylinder head.
3. Using several steps, uniformly install and tighten the 10 cylinder head bolts and 10 plate washers with a 10 mm bi-hexagon wrench in the order shown in the illustration.

2. Align the mark plate (orange) with the timing mark of the No. 2 camshaft as shown in the illustration and install the chain.

   HINT:

   • Be sure to position the mark plate at the front of the engine.
   • The mark plate on the camshaft side is colored orange.
   • Do not pass the chain around the sprocket of the camshaft timing gear assembly. Only place it on the sprocket.
   • Pass the chain through the No. 1 vibration damper.

4. Hold the hexagonal portion of the camshaft with a wrench and turn the camshaft timing gear assembly counterclockwise to align the mark plate (orange) and timing mark.

   HINT:

   • Be sure to position the mark plate at the front of the engine.
   • The mark plate on the camshaft side is colored orange.
5. Hold the hexagonal portion of the camshaft with a wrench and turn the camshaft timing gear assembly clockwise.

   HINT:

   To tension the chain, slowly turn the camshaft timing gear assembly clockwise to prevent the chain from being misaligned.
