Exhaust Manifold And Three Way Catalyst: Installation

WARNING: This page is about a different car, the 2007 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

Installation is in the reverse order of removal.

Install the exhaust manifold nuts in the order as shown.
CAUTION:
- When using the heated oxygen sensor wrench, tighten to the middle of specified torque range, because the length of the Tool may increase the actual tightness. Do not tighten to the maximum specified torque range.
