Installation Procedure
WARNING: This page is about a different car, the 2003 GMC Savana and 2003 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.
Important: It is normal for NEW lifters to make a slight ticking noise when the engine is first started. Increasing the engine RPMs slightly to raise oil pressure should stop the noise.
- Apply lubricant GM P/N 12345501 (Canadian P/N 992704) or equivalent to the valve lifter rollers.
Important: If reusing the valve lifters, install the valve lifters in the original positions.
- Install the valve lifters.
CAUTION: 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.
- Install the valve lifter pushrod guides.
Tighten
Tighten the valve lifter pushrod guide bolts to 16 N.m (12 lb ft).
