Removal & Installation
- On models with double exhaust manifold outlets, oxygen sensor is mounted in exhaust pipe just below exhaust header. On models with single outlet exhaust manifold, oxygen sensor is mounted in exhaust manifold before the catalytic converter.
- Protect oxygen sensor electrical connector from damage when removing sensor. Ensure sensor is free of contaminants. Avoid using cleaning solvents of any type. Sensor may be difficult to remove when engine temperature is less than 120°F (49°C). Always use anti-seize compound on threads prior to installation. Tighten sensor to specification.
