5. Disconnect the exhaust pressure tube from the LH exhaust manifold.
6. Remove the 8 bolts, 8 spacers and the LH exhaust manifold.
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 and tighten the bolts in the sequence shown.
^ Tighten to 38 Nm (28 ft. lbs.).
2. Connect the exhaust pressure tube to the exhaust manifold.
^ Tighten to 30 Nm (22 ft. lbs.).
3. NOTE: Apply anti-seize lubricant to the bolt threads prior to installing the bolts.
