- Coat the valve lifters with engine assembly prelube GM P/N 1052367, or equivalent.
- Install the valve lifters in the lifter bores.
- Install the lifter guides on the valve lifters.
- Install the bolts that retain the lifter guides.
Notice: If the valve lifters and anti-rotation brackets are not installed properly, the valve lifters, the anti-rotation brackets, and the engine could be damaged.
Important: When installing valve lifters, coat the lifters with engine assembly prelube GM P/N 1052367, or equivalent.
| • | Align the flat sides, top, of the lifters with the flat sides of the lifter guides. |
| • | When properly aligned, the flat side of each lifter is aligned parallel to the lifter guide. |
| • | The roller at the bottom of each lifter is aligned parallel to the camshaft lobe. |
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.
Tighten
Tighten the lifter guide bolts to 11 N·m (97 lb in).
