Drain the coolant from the cooling system into a suitable container for storage or disposal. Refer to Operation and Maintenance Manual, "Cooling System Coolant - Change" for the correct procedure.
Prior to and during removal of bolts (2) and bolts (10) apply releasing fluid to the bolts. Remove bolts (2) and bolts (10) from tube assembly (3).
Remove tube assembly (3) from the exhaust cooler and the exhaust manifold.
Remove gasket (1) (not shown) and gasket (9) (not shown) from tube assembly (3).
Remove bolts (5) and bolt (8) from tube assembly (4).
Remove tube assembly (4) from the cylinder head and the exhaust cooler.
Remove gasket (6) (not shown) and O-ring seal (9) (not shown) from tube assembly (4).

Illustration 3 g02477643
Loosen bolts (12) in reverse numerical order. Refer to Illustration 2. Note: Loosen the bolts in reverse numerical order will help prevent distortion of the exhaust manifold.
Remove bolts (12) and spacers (11) from exhaust manifold (13). Note position of the different length spacer. Note: Support the manifold as the bolts are removed.
Remove exhaust manifold (13).
Remove exhaust manifold gasket (14) (not shown). Installation Procedure

Required Tools
Tool Part Number Part Description Qty
A 366-1820 Manifold Alignment Pins 2
B 377-2038 Manifold Alignment Pins 1
C(1) - Loctite 575 1
(2)D - Loctite 565 1
(1) If Loctite 575 is not available, install new bolts
(2) If Loctite 565 is not available, install new bolts
Ensure that the exhaust manifold is clean and free from damage. If necessary, replace the exhaust manifold. Clean the gasket surface of the cylinder head.

Tighten sequence of exhaust manifold and Tooling position
Illustration 5 g02477643
Position a new exhaust manifold gasket (14) (not shown) onto the cylinder head. Install Tooling (A) in Positions (X) and Tooling (B) in Positions (Y). Refer to Illustration 4. Note: Ensure that the exhaust manifold gasket is correctly oriented.
Align exhaust manifold (13) with Tooling (A) and Tooling (B). Install the exhaust manifold to the cylinder head.
If bolts (12) have been previously used, thoroughly clean the bolts. Tooling (C) or Tooling (D) should be applied to the first two threads of the bolts. If Tooling (C) or Tooling (D) is not available, new bolts should be installed. Note: Do not apply Tooling (C) or Tooling (C) to new bolts.
Install bolts (12) and spacers (11) hand tight. Ensure that the different length spacer is installed into the correct position.
Remove Tooling (A) and Tooling (B). Install remaining bolts (12) and spacers (11) hand tight.
Tighten bolts (12) to a torque of 44 N m (32 lb ft). Tighten the bolts in the sequence that is shown in Illustration 3.
Illustration 6 g02477639
Position a new gasket (6) (not shown) and a new O-ring seal (9) (not shown) onto tube assembly (4).
Install tube assembly (4) to the cylinder head and the exhaust cooler. Note: Ensure that the tube assembly is correctly installed into the exhaust cooler.
Install bolts (5) and bolt (8) to tube assembly (4).
Tighten bolt (8) to a torque of 18 N m (159 lb in). Tighten bolts (5) to a torque of 22 N m (195 lb in).
Position a new gasket (1) (not shown) and a new gasket (9) (not shown) to tube assembly (3).
Install tube assembly (3) to the exhaust cooler and the exhaust manifold.
Install new bolts (2) and new bolts (10) to tube assembly (3). Tighten the bolts to a torque of 22 N m (195 lb in).
Fill the cooling system with coolant. Refer to Operation and Maintenance Manual, "Cooling System Coolant - Change" for the correct procedure. End By:
Install the first stage turbocharger for twin turbocharged engine. Refer to Disassembly and Assembly, "Turbocharger (First Stage Turbocharger) - Install" for the correct procedure.
Install the second stage turbocharger for twin turbocharged engine. Refer to Disassembly and Assembly, "Turbocharger (Second Stage Turbocharger) - Install" for the correct procedure.
