To install:
- Make sure that the drift is installed into the camshaft adjuster.
- Align the pin with the hole in the end of the camshaft to install the camshaft adjuster on the intake camshaft.
- When the camshaft is correctly aligned on the camshaft adjuster, the alignment marks on the back of the camshaft adjuster will be lined up and the camshaft will seat all of the way into the adjuster.
- Install the intake and exhaust camshafts into the cylinder head so that the horizontal alignment marks line up with the top edge of the cylinder head and the vertical alignment mark is pointed upwards.

- Draw the timing chain up through the left cylinder head.
- Assemble the chain using a new link.
- Remove the drift from the left camshaft adjuster.
- Install a new camshaft timing wheel on the intake camshaft in the left cylinder head. Rotate the timing wheel until the wheel sits flush on the camshaft. There is a dimple in the camshaft and a matching dimple in the timing wheel. Make sure that the camshaft timing wheel dimples line up.
- Install the left camshaft adjuster center bolt finger tight.
- Remove the drift from the right camshaft adjuster.
- Install a new camshaft timing wheel on the intake camshaft in the right cylinder head. Rotate the timing wheel until the wheel sits flush on the camshaft. There is a dimple in the camshaft and a matching dimple in the timing wheel. Make sure that the camshaft timing wheel dimples line up.
- Install the right camshaft adjuster center bolt finger tight.
- Make sure the front cover o-rings at the water pump inlet and outlet are intact and in place.
