Exhaust manifolds — removal and installation
Warning: The engine must be completely cool before beginning this procedure.
Note: The following procedure applies to either exhaust manifold.
1. Disconnect the electrical connectors from the left upstream oxygen sensor.
2. Remove the bolts that secure the exhaust manifold support bracket and remove it.
3. Disconnect any interfering wire clamps.
4. Remove the heat shield from the front exhaust manifold.
5. Evenly loosen the nuts that secure each exhaust manifold and remove the exhaust manifold.
6. Remove and discard the old exhaust manifold gasket.
7. Installation is the reverse of removal. Be sure to use a new gasket and install it with the oval-shaped protruding tip facing in the correct direction. For the left (driver’s side) manifold, the tip must face to the rear; on the right manifold, it must face to the front.
8. Tighten the exhaust manifold nuts a little at a time, working from the center nuts outward, to the torque listed in this Chapter’s Specifications.
