OTC introduces new Fuel Sender Lock Ring Wrench for select Cadillac models.

OTC has announced the new 6556 Fuel Sender Lock Ring Wrench that is designed for removing the newly-designed 4-1/2” fuel sender lock ring on 2003-2011 Cadillac CTS, SRX and STS models.

The three-prong fuel sender lock ring requires high torque to loosen and tighten, requiring a specialized wrench for service. The 3/8” square drive is centered for even and full application of torque to remove and install lock rings.

The 6556 Fuel Sender Lock Ring Wrench is similar to the essential tool J-45747, required to service 2003 – 2011 CTS, SRX, and STS models. It is covered by OTC’s lifetime warranty and is available now in North America from tool dealers nationwide.
