  Q: How to service and repair the Fuel Level Sensor on Buick Rendezvous?

  A:

  Football unit replacement should start with removing the fuel sender assembly before disconnecting both the fuel pump electrical connector and the fuel level sensor electrical connector retaining clip. The service starts by removing the fuel level sensor electrical connector from where it sits under the fuel sender cover then removing the fuel level sensor retaining clip. You can move the fuel level sensor out of the modular fuel sender by compressing its locking tangs. The modular fuel sender requires the fuel level sensor insertion followed by retaining clip installation to secure it. Before reinstalling the fuel sender assembly participants must reconnect the fuel level sensor electrical connector and install its retaining clip followed by the reconnection of the fuel pump electrical connector . To inspect for fuel leaks, activate the ignition for 2 seconds followed by turning it OFF for 10 seconds and conducting another check for fuel leakage by repeating the turn ON process.

  Q: How to Replace a Fuel Level Sensor in a Fuel Sender Assembly on Buick Rendezvous?

  A:

  The Fuel Level Sensor replacement starts with removing the Fuel Tank while also disconnecting the fuel sender module electrical connectors along with strict caution to avoid touching the fuel tubes because holding the Fuel Level Sensor by the fuel pipes could damage their joints. You should use the fuel sender lock ring wrench (J 45722) to disconnect fuel pipes from the Fuel Level Sensor while preventing lock ring damage. The proper method to unlock the Fuel Level Sensor lock ring requires j 45722 and a long breaker-bar to turn the ring counterclockwise without impact tools. Dismount the Fuel Tank lock ring and the Fuel Level Sensor with the fuel sender seal destined for discard. Check the fuel sender module lock ring for damage while inspecting its flatness during the procedure of removing the Fuel Level Sensor from the fuel sender module. It is necessary to replace the lock ring when the deformation exceeds 0.41 mm (0.016 in). The installation process requires proper attachment of the Fuel Level Sensor to the fuel sender module followed by cleaning the fuel sender sealing flange before installing the fuel sender seal when replacing the Fuel Level Sensor. The j 45722 tool enables clockwise installation of the fuel sender lock ring during the Fuel Level Sensor setup. The final steps consist of restoring the fuel pipes to attach with the Fuel Level Sensor followed by setting up the fuel sender sensor electrical connections then installing the Fuel Tank.
