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.
Valve Timing: Description
The timing drive system (Fig 1 ) has been designed to provide quiet performance and reliability to support a NON free-wheeling engine.
The timing drive components include a crankshaft sprocket, camshaft sprockets, tensioner pulley, hydraulic tensioner and a timing belt. The water pump is driven by the back side of the timing belt. The right and left camshaft sprockets are not interchangeable because of the cam sensor pick-up wheel on the left sprocket.
