For 1990-2009 cars only
- Apply a liberal amount of lubricant GM P/N 12345001 or equivalent to the roller (2), pivot pocket and valve slot areas (1) of the camshaft followers.
- Place the camshaft followers in position on the valve tip and stationary hydraulic lash adjuster (SHLA). The rounded head of the follower goes on the SHLA while the flat end goes on the valve tip.
Important: The follower must be positioned squarely on the valve tip so that the full width of the roller will completely contact the camshaft lobe. If the followers are being reused you must put them back in their original location.
