How to Service and Repair the Rocker Arm Assembly on Chevrolet Colorado?

One must remove the camshaft cover before starting the valve Rocker Arm and valve Lash Adjuster replacement. When the Crankshaft reaches the open position of the affected cylinder valve ensure the cam lobe fully compresses the spring. The en-47945 valve spring compressor (EN-47945) needs installation on the engine Cylinder Head through either one or two of the supplied fasteners placed in the coil fastener hole but one fastener works in specific areas. Perform engine rotation to reach the base circle of the cam instead of using the tool while rotating the engine since Piston contact may damage the valves. When positioning the cam on its base circle the spring stays compressed to manage the valve Rocker Arm and valve Lash Adjuster removal. Perform cleaning along with inspection of both components before you conduct lubrication on the valve Rocker Arm while adding oil to the valve Lash Adjuster. Place the valve Rocker Arm along with the valve Lash Adjuster in position before turning the engine clock-wise until the spring reaches its complete depression by the cam lobe. Take out the en-47945 from the Cylinder Head then perform the process again if needed. Finally, install the camshaft cover.
