Exhaust Manifold - LH













Removal

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Vehicle Jacking and Lifting.

2. Remove the engine cover.

3. Prior to removing the exhaust manifold, inspect the exhaust manifold for warpage with a feeler gauge between the manifold and the cylinder head. Record the measurement and compare with the specifications.

4. Remove the 2 LH exhaust manifold-to-turbocharger adapter pipe nuts.
- Discard the nuts.

5. Disconnect the Exhaust Pressure (EP) tube from the LH exhaust manifold.

6. Remove the 8 bolts, 8 spacers and the LH exhaust manifold.
- Discard the bolts.

Installation

1. NOTE: Start installing the bolts with the second bolt from the rear on the top. The hole diameter is smaller, therefore allowing alignment of the remaining bolts.

NOTE: When installing the exhaust manifolds, only use prevailing torque hex flange bolts with an interference fit.

NOTE: Apply anti-seize lubricant to the bolt threads prior to installing the bolts.

Install the LH exhaust manifold, 8 spacers and 8 new bolts. Tighten the bolts in the sequence shown.

- Tighten to 38 Nm (28 lb-ft).





2. Connect the EP tube to the exhaust manifold.
- Tighten to 30 Nm (22 lb-ft).

3. NOTE: Apply anti-seize lubricant to the bolt threads prior to installing the bolts.

Install the 2 new LH exhaust manifold-to-turbocharger adapter pipe nuts.

- Tighten to 27 Nm (20 lb-ft).

4. Install the engine cover.
