Exhaust Manifold

Exhaust Manifold Installation - Right Side (W/O RPO NC1 or NF7)

Position a new manifold gasket (1) in place on the cylinder head studs.

Using two hands, position the manifold (2) onto the cylinder head.

Install two outer manifold nuts (3) to hold the manifold in place.

Install the remaining manifold nuts.
Tighten the exhaust manifold nuts (3) to 25 N.m (18 lb ft).

Exhaust Manifold Installation - Right Side (With RPO NC1 or NF7)

With the manifold still on the bench, position a new manifold gasket (1) in place on the manifold sealing surface.

Install 2 outer manifold bolts (6) in the manifold to retain the gasket.

Install a new manifold to intermediate pipe flange gasket (5).

Using 2 hands, place the manifold (2) in the intermediate pipe and onto the cylinder head.

Install new manifold flange bolts (3) for maximum joint integrity. Hand tighten. Do not torque the flange bolts to specification until the engine is mounted in the vehicle.

Hand tighten the 2 outer manifold bolts.

Install the remaining manifold bolts.
Tighten the exhaust manifold bolts (6) to 25 N.m (18 lb ft).

Exhaust Manifold Installation - Left Side (With RPO NC1 or NF7)

DO NOT reuse the exhaust manifold gasket.

With the manifold still on the bench, position a new manifold gasket (1) in place on the manifold sealing surface.

Install 2 outer manifold bolts (6) in the manifold to retain the gasket.
