CAUTION: Apply the proper amount of the sealant when assembling this component. Excessive use of the sealant can prohibit the component from sealing properly. A component that is not sealed properly can leak leading to extensive engine damage.

Apply a 4.0 mm (0.157 in) patch of adhesive GM P/N 12346141 (Canadian P/N 10953433) or equivalent, to the cylinder head side of the lower intake manifold gasket at each end.

NOTE: The lower intake manifold gasket must be installed while the adhesive is still wet to the touch.

Install the lower intake manifold gasket onto the cylinder head.
Use the gasket locator pins in order to properly seat the lower intake manifold gasket on the cylinder head.

NOTE: The lower intake manifold must be installed and the fasteners tightened while the adhesive is still wet to the touch.

Apply a 5 mm (0.197 in) bead of adhesive GM P/N 12346141 (Canadian P/N 10953433) or equivalent, to the front top of the engine block.
Extend the adhesive bead 13 mm (0.50 in) onto each lower intake manifold gasket.

Install the lower intake manifold onto the engine block.
If reusing the fasteners, apply threadlock GM P/N 12345382 (Canadian P/N 10953489) or equivalent, to the threads of the lower intake manifold bolts.
Install the lower intake manifold bolts.

Fig 5: Lower Intake Manifold Bolt Tightening Sequence

CAUTION: Proper lower intake manifold fastener tightening sequence and torque is critical. Always follow the tightening sequence, and torque the intake manifold bolts using the 3 step method. Failing to do so may distort the crankshaft bearing bore alignment and cause damage to the crankshaft bearings.

CAUTION: Refer to Fastener Caution .

Tighten the lower intake manifold bolts.
1. Tighten the bolts on the first pass in sequence (1-8) to 3 N.m (27 lb in).
2. Tighten the bolts on the second pass in sequence (1-8) to 12 N.m (106 lb in).
3. Tighten the bolts on the final pass in sequence (1-8) to 15 N.m (11 lb ft).
