5. Install the exhaust manifold heat shield and bolts. Tighten the bolts to 10 Nm (89 lb in).
Note: A special anti-seize compound is used on the HO2S threads. The compound consists of graphite suspended in fluid and glass beads. The
graphite will burn away, but the glass beads will remain, making the sensor easier to remove. New or service sensors will already have the
compound applied to the threads. If a sensor is removed from an engine and is to be reinstalled, the threads must have anti-seize compound applied
before the reinstallation.
6. Coat the threads of the HO2S with anti-seize compound. Refer to Adhesives, Fluids, Lubricants, and Sealers (See: Specifications/Fluid Type
Specifications)
7. Install the HO2S using J 39194-B. Tighten the sensor to 42 Nm (31 lb ft).
