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.
- Apply a 5 mm (0.197 in) bead of adhesive GM P/N 12346141
(Canadian P/N 10953433) or equivalent, to the rear 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.
Caution: Refer to Fastener Caution in the Preface section.
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.
- Tighten the lower intake manifold bolts.
10.1. | Tighten the bolts on the first pass in sequence (1-8) to
3 N·m (27 lb in). |
10.2. | Tighten the bolts on the second pass in sequence (1-8) to
12 N·m (106 lb in). |
10.3. | Tighten the bolts on the final pass in sequence (1-8) to
15 N·m (11 lb ft). |
- Connect the evaporative emission (EVAP) canister solenoid valve harness.
11.1. | Push the elbow inward until the quick connect snaps into place. |
11.2. | Pull the elbow outward in order to ensure proper connection. |
- Install a NEW oil pump drive shaft gasket onto the oil pump drive shaft.
- Install the oil pump drive shaft and
oil pump drive shaft clamp.
- Install the oil pump drive shaft bolt. Tighten the oil pump drive shaft clamp bolt to
25 N·m (18 lb ft).
- If required, install the ignition coil bracket and bolts. Tighten the ignition coil bracket bolts to
12 N·m
(106 lb in).
- Install the ignition coil and ignition coil bolts and tighten to
12 N·m (106 lb in).
