Removal
Although the camshaft timing belt does not need to be removed completely, it will need to be removed from the camshaft pulley(s). Use extreme caution to protect the belt from bending, twisting, and contamination with oil or coolant.
1. Turn the crankshaft pulley until cylinder number 1 is at Top Dead Center on the compression stroke. Check that the pointer on the back of the cylinder block is aligned with the white mark on the flywheel.
2. Remove the valve cover. Remove the upper camshaft drive belt cover.
3. Loosen, but do not remove, the tensioner adjusting bolt and pivot bolt.
4. Move the camshaft drive belt off the camshaft sprocket. The belt may remain inside the covers.
5. To remove the camshaft sprocket, remove the center bolt and then remove the sprocket using a pulley puller or brass hammer. The pulley is centered on the shaft using a special key or guide device; don't lose it.
To install:
6. Make sure that the end of the camshaft is positioned with the groove facing upwards. If necessary, the camshaft(s) can be turned by the faceted casting located in the middle of the camshaft; use an adjustable wrench.
7. Install the key or guide device, then install the pulley. Make sure the original washer is reinstalled with the locking bolt. Tighten the locking bolt to 38 Nm.
8. Ensure that the camshaft pulley(s) are properly aligned; the marks on the edges of the pulleys should be aligned with the surface of the head. Carefully slide the camshaft drive belt onto the pulley(s),
9. Rotate the crankshaft counterclockwise until the camshaft pulley turns 3 teeth. Adjust the camshaft drive belt tension with the adjuster. Tighten the adjusting bolt to 43 Nm.
10. Install the upper timing belt cover and valve cover.
11. Run the engine at idle speed. Carefully check the work area for any sign of fluid leakage or the presence of a sound of beating or vibration of connections.
