Required Tools
Tool Part Number Part Description Qty
B(1) 366-1820 Manifold Alignment Pins 2
C(2) 366-1819 Manifold Alignment Pins 2
(1) Tooling (B) is used to hold the gasket in position and align the exhaust manifold.
(2) Tooling (C) is used to align the exhaust manifold.
Ensure that wiring harness are correctly routed and the cable straps are not over tightened. Over tightening of the cable straps will damage the wiring harness convoluting.

Ensure that exhaust manifold (19) is clean and free from damage. If necessary, replace the exhaust manifold. Clean the gasket surface of the cylinder head.
Position a new exhaust manifold gasket (21) (not shown) onto the cylinder head. Install Tooling (B) in Position (X). Install Tooling (C) in Position (Y). Refer to Illustration 5.Note: Ensure that the exhaust manifold gasket is correctly oriented.
Position a new exhaust manifold gasket (22) (not shown) onto the cylinder head. Install Tooling (B) in Position (X). Install Tooling (C) in Position (Y). Refer to Illustration 5.Note: Ensure that the exhaust manifold gaskets are correctly oriented.
Position a new gasket (27) (not shown) onto a new tube assembly (25). Position tube assembly onto the NRS exhaust cooler and install new bolts (26) and tighten the bolts ensuring that the tube assembly can still move.
Position a new gasket (23) (not shown) onto tube assembly (25)
Align exhaust manifold (19) with Tooling (A). Install the exhaust manifold to the cylinder head.
Install bolts (24) for tube assembly (25) and tighten the bolts ensuring that the tube assembly can still move.
Install new bolts (20) and the spacers in the eight available position to exhaust manifold (19).
Tighten bolts (20) one to four to a torque of 44 N m (32 lb ft). Tighten the bolts in the sequence that is shown in Illustration 5.
Remove Tooling (A). Install remaining new bolts (20) and the spacers to exhaust manifold (19).
Tighten remaining bolts (20) to a torque of 44 N m (32 lb ft). Tighten the bolts in the sequence that is shown in Illustration 5.
Tighten bolts (24) and bolts (26) for tube assembly (25) to a torque of 22 N m (195 lb in).
