Verona L6-2.5L (2005)
CAUTION: The oxygen sensor may be difficult to remove when the engine temperature is below 118 °F (48 °C). Excessive force may damage
the threads in the exhaust manifold.
Oxygen Sensor (O2S) Installation
1. Installation should follow the removal procedure in the reverse order.
NOTE: A special anti-seize compound is used on the O2S threads. This compound consists of a liquid graphite 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 any engine and if for any reason it is to be reinstalled, the threads must have anti-seize compound applied
before reinstallation.
2. Install the oxygen sensor (O2S).
Tighten: Tighten the oxygen sensor to 34 ~ 44 N.m (25 ~ 32 lb.ft).
3. Install the exhaust manifold shields.
Tighten: Tighten the exhaust manifold heat shield bolts to 18 ~ 22 N.m (13 ~ 16 lb.ft).
