OEM 2010 Cadillac CTS Fuel Level Sensor

2010 Cadillac CTS Parts Questions & Experts Answers

• Q: How to replace the Fuel Level Sensor on the left side on 2010 Cadillac CTS?

  A: One must start by removing the Fuel Tank to exchange the left side Fuel Level Sensor because this exposes the secondary Fuel Tank module. Pull out the electrical connector from the secondary Fuel Tank module before placing it to one side. You should use only the j 45722 to unlock the Fuel Tank module lock ring through counterclockwise turning with a long breaker-bar but maintain lock ring protection. The cam lock ring should be removed before pulling out the secondary Fuel Tank module partially for access to the fuel transfer hose quick connect fitting. It's essential to avoid damaging the float arm. Unplug the fast-connect fitting on the fuel transfer hose then take out the secondary Fuel Tank module along with its Fuel Tank module seal which needs disposal. The lock ring needs examination for signs of damage. Replace the lock ring if it deforms beyond 0.41 mm (0.016 in). A new Fuel Tank module seal needs to be used during installation while simultaneously connecting the fuel transfer hose quick connect fitting to the Fuel Tank module. The enclosed ring must be properly positioned while installing the secondary Fuel Tank module before tightening the clock-wise oriented lock ring. A j 45722 with a long breaker-bar allows users to install the Fuel Tank module lock ring by turning it clockwise until it reaches full seat position. Reverse the procedure by connecting the electrical connector to the secondary Fuel Tank module while activating the connector interlock lock before placing back the Fuel Tank.
