Connecting Rod Final Assembly Procedure

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.

Guide the connecting rod away from the crankshaft connecting rod journal to lubricate the crankshaft connecting rod bearing journal.
Apply a liberal amount of crankshaft prelube to the crankshaft connecting rod bearing journal. Adhesives, Fluids, Lubricants, and Sealers
Guide the connecting rod to the crankshaft connecting rod journal.
Install the connecting rod end cap (4) on its original connecting rod (1) and ensure the bearing lock tangs are aligned on the same side of the rod.
CAUTION:
Do not lubricate the NEW connecting rod bolts. The NEW bolts have a pre-applied graphite lubricant. Applying lubricant to the connecting rod bolts will effect the clamp load when the connecting rod bolts are torqued. Improper clamp load can lead to component failure and extensive engine damage.

CAUTION:
This vehicle is equipped with torque-to-yield or single use fasteners. Install a NEW torque-to-yield or single use fastener when installing this component. Failure to replace the torque-to-yield or single use fastener could cause damage to the vehicle or component.

Install the NEW connecting rod bolts (5) into the connecting rod cap (4).
Tighten the connecting rod bolts (5). Fastener Specifications
During and after installation, ensure each piston is positioned properly in the correct cylinder. The locating arrow on the top of each piston must be pointing toward the front of the engine.
Repeat these procedures for the remaining piston/connecting rod assemblies using the EN-48589 Crankshaft Rotation Socket to rotate the crankshaft.
NOTE:
- Install and align the crankshaft rear oil seal housing within 10 minutes of applying the sealer.
- Ensure proper use of room temperature vulcanizing (RTV) sealant. Use of Room Temperature Vulcanizing (RTV) and Anaerobic Sealant
- DO NOT allow any engine oil on the area where the crankshaft rear oil seal housing is to be installed.
Apply a 3 mm (0.118 in) bead of RTV sealant around the perimeter of the NEW crankshaft rear oil seal housing (1). Adhesives, Fluids, Lubricants, and Sealers
