WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
- Install the lower intake manifold gaskets.
- Coat the ends of the push rods using prelube GM P/N 12345501 (Canadian P/N 992704) or the equivalent.
- Install the push rods in their original location.
- Coat the rocker arm friction surfaces using prelube GM P/N 12345501 (Canadian P/N 992704) or the equivalent.
- Install the valve rocker arms in their original positions.
- Install the valve rocker arm bolts.
Tighten: Tighten the valve rocker arm bolts to 34 N.m (25 lb ft).
IMPORTANT:
All gasket mating surfaces must be free of oil and foreign material. Use GM P/N 12346139 (Canadian P/N 10953463) or equivalent to clean surfaces.
IMPORTANT:
Room temperature vulcanizing (RTV) sealer is not to be placed under the lower intake manifold gaskets.
IMPORTANT:
The intake valve push rods measure 147.51 mm (5.81 in) and the exhaust valve push rods measure 154.87 mm (6.1 in) in length.
IMPORTANT:
Shims (P/N 88894006) may be required under the valve rocker arm pedestals if reconditioning has been performed on the cylinder head or its components.
NOTE:
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.
NOTE:
