2006 Cadillac STS Lash Adjuster Parts and Q&A

• Q: How to replace the right lash adjuster on 2006 Cadillac STS?

  A: The replacement process for right lash adjusters begins by removing right valve rocker arms but must maintain each camshaft follower's position relative to its original stationary hydraulic Lash Adjuster (SHLA) and location. Clean and examine the lash adjusters before you install the shla into right cylinder head bores. Place the number one cylinder Crankshaft at its top dead center position before adding clean engine oil (GM P/N 12378006 or equivalent) to the shla while avoiding contact with the pivot sphere area. Clean engine oil (GM P/N 12378006 equivalent) should serve as the lubricant for shla bores in the cylinder head before positioning the shla in its proper bore placement followed by right valve Rocker Arm reinstallation.
