How to install the oxygen r?

Step 1 - Some rs are equipped with a heat shield that must be removed before the r removal, this is performed by removing any mounting bolts.

Step 2 - By using a regular socket it minimizes potential damage to the r body and the threads, this technique helps avoid stripping the old r upon removal.

Step 3 - Then, locate and disconnect the wiring connector, this step should be done before removing the r if the wiring is still attached.

Step 4 - Its important that the wiring harne connectors are exactly the same, each r is unique to it's position and is located in the system by its connector configuration. (Note: some replacement rs have a universal electrical connector that must be configured to the wiring of the old r.)

Step 5 - Use a small wire brush to help clean the threaded port to ensure a proper seal of the new r. Gently install the new oxygen r by hand while keeping the wiring and connector free from bends.

Step 6 - Gently tighten the r while keeping wiring free from damage, these rs need to be fairly snug to avoid leakage.

Step 7 - Once the r is tightened, reinstall any heat shields or bracing that had to be removed.

Step 8 - After the heat shield has been reinstalled, mount the connector to it's holder and reattach the connector back onto the wiring harne. If the car has diagnostic trouble codes, they will need to be cleared.
