Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Engine Timing - Verification
Correct timing is critical for the NON free-wheeling designed, 2.7L engine. Engine timing can be verified by using the following procedures:
- Remove cylinder head covers. (Refer to REMOVAL ).
- Rotate engine until number one cylinder is at TDC on the EXHAUST stroke.
- View the intake camshaft sprocket timing mark. The mark should be 90° from the cylinder head cover sealing surface (Fig 1) on both right and left cylinder banks.
- Count chain pins from the mark on the intake camshaft towards the exhaust camshaft. Engine is timed correctly when there are 12 chain pins between the timing marks on the intake camshaft and exhaust camshaft (Fig 1).
- If marks are not correctly aligned, proceed to Timing Chain and Sprockets for service procedures. (Refer to REMOVAL ).
