  Q: How to install the valve pushrods and valve rocker arm assemblies correctly on GMC Jimmy?

  A:

  Before installing the valve rocker arm supports maintain an upwards position of the arrow on the valve rocker arm support. Apply prelube GM P/N 12345501 (Canadian P/N 992704) or equivalent to three main contact areas of valve rocker arms: valve pushrod socket , roller pivot , and valve stem tip . Start by installing the bolt at positions and before moving to and then continue with all valve rocker arm bolts. During this step proceed to position the number 1 cylinder at top dead center (TDC) compression stroke while keeping crankshaft balancer marks properly aligned with the front cover tabs. The installation requires proper fasteners to be used exactly where specified because replacement fasteners must match their specified part numbers. Use paint and lubricants or corrosion preventives only when directed because they may alter the clamping force and torque measurements. Correct fastener sequence along with tightening specifications must be followed to avoid damage to the components. The installed valve rocker arm assemblies require torque at 30 Nm (22 ft. lbs.) and subsequent valve lash adjustment will not be needed.
