Installation Procedure

Illustration 2	g00825291
Typical example

1. If studs (2) were removed during disassembly, install attaching studs (2) to cylinder head (1) .

2. Put a new exhaust manifold gasket (3) in position on cylinder head (1) .

   Note: Do not use any sealant on the exhaust manifold gasket.

3. Put exhaust manifold (4) in position on cylinder head (1) .

4. Install exhaust manifold nuts (5) and bolts (6) .

   For 3013C Engines and 3024C Engines, tighten nuts (5) and bolts (6) to a torque of 25 N·m (18 lb ft).

   For 3011C Engines, tighten nuts (5) and bolts (6) to a torque of 10 N·m (89 lb in).

   Note: Tighten the two inner bolts first on three cylinder engines. Tighten the four inner bolts first on four cylinder engines. Then tighten the two outer bolts and the two nuts. Ensure that the bolts with different lengths are installed in the correct holes.
