Malibu L4-2.4L (2010)
1. Install a NEW gasket (6) to the catalytic converter.
2. Install the right (rear) catalytic converter (2).
Caution: Refer to Fastener Caution (See: Service Precautions/Vehicle Damage Warnings/Fastener Caution).
3. Install the right (rear) catalytic converter bolt (5) and nuts (1) at the exhaust manifold and tighten to 45 Nm (33 lb ft).
4. Install the left (front) catalytic converter to right (rear) catalytic converter nuts (3) and tighten to 25 Nm (18 lb ft).
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.
5. If reinstalling the old HO2S, coat the threads with anti-seize compound. Refer to Adhesives, Fluids, Lubricants, and Sealers (See:
Specifications/Fluid Type Specifications)
6. Install the lower right HO2S (2) using the J 39194-B. Tighten the sensor to 42 Nm (31 lb ft).
