Oxygen (O2) Sensors: Installation

WARNING: This page is about a different car, the 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.

If installing original or used downstream oxygen sensor, apply anti-seize compound on threads of downstream oxygen sensor. A NEW downstream oxygen sensor should already be coated with anti-seize compound. Install and tighten downstream oxygen sensor to specification. See TORQUE SPECIFICATIONS .
