Notice: Prime the new valve lifters before installation. The valve lifters may
be damaged if the valve lifters are dry when the engine is started.
- Connect the valve lifters to the engine.
Important:
⢠| Prime the new valve lifters before installation by working the
valve lifter plunger while submerged in clean engine oil. |
⢠| Coat the valve lifter roller and bearings with lubricant GM P/N
1052365 or equivalent. |
⢠| The valve lifters must be installed in their original locations. |
- Install the plates.
Important: The straight edge of the guide plates and clamps face away from the
cylinder.
- Install the clamps.
Tighten
Tighten the clamp bolt to 26 NĀ·m (18 lb ft).
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
Important: After all the clamps are installed, turn the crankshaft by hand two
full revolutions, to ensure free movement of the valve lifters in the plate.
If the engine will not turn over by hand, one or more of the valve lifters
may be binding in the plate.
