WARNING: This page is about a different car, the 2002 Pontiac Sunfire and 2002 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

Tools Required: J 36660-A Torque Angle Meter

Install the main bearings and lubricate with engine oil.
Install the crankshaft on the journals.
NOTE: In order to prevent the possibility of cylinder block or crankshaft bearing cap damage, the crankshaft bearing caps are tapped into the cylinder block cavity using a brass, lead, or a leather mallet before the attaching bolts are installed. Do not use attaching bolts to pull the crankshaft bearing caps into the seats. Failure to use this process may damage a cylinder block or a bearing cap.
Install the crankshaft caps. Tap gently into place with a suitable tool.
Install the crankshaft cap bolts. Finger tighten the bolts.
