7. Remove the bolts, nuts, and the exhaust manifold and gasket.

To Install:

1. Clean the mating surfaces for the exhaust manifold and cylinder head.
2. Install a new gasket and the exhaust manifold. Tighten the bolts in the sequence shown below. Torque the bolts in two steps:
   • Step 1: Tighten to 8 ft. lb. (10 Nm).
   • Step 2: Tighten to 17 ft-lb (23 Nm).

   Tighten the exhaust manifold bolts in sequence-3.0L left side

3. Install the upper intake manifold support brace.
   • Torque to 89 in-lb (10 Nm).

   NOTE: The end of the dipstick tube must be cleaned with metal parts cleaner before application of the sealant.

4. Install the dipstick and tube assembly. Coat the dipstick tube with silicone sealant.
5. Install the dipstick tube bracket nut.
   • Torque to 13 ft-lb (18 Nm).
6. Install the exhaust flange nuts.
   • Torque to 30 ft-lb (40 Nm).
7. Connect the negative battery cable.
8. Start the vehicle and check for leaks, repair if necessary.

Right Side

3. Disconnect the negative battery cable.
4. Remove the exhaust flange nuts.
5. Remove the exhaust manifold bolts and stud bolts.
6. Remove the exhaust manifold gasket and the exhaust manifold.

To Install:

1. Clean the mating surfaces for the exhaust manifold and cylinder head.
2. Place the exhaust manifold gasket and the exhaust manifold in the correct position.
3. Install the bolts and nuts then torque in the following sequence:
