Would this be the O2 Sensor I would need for my 2003 Jeep Liberty for Bank 1 Sensor 1?
Gavin on Aug 5, 2017
BEST ANSWER: Yes, this will work. This tool is used to tighten the new O2 sensor. To get the old sensor off you will probably need to cut the wires at the old sensor and use a regular deep socket to remove the old sensor. This slotted socket will probably not be able to maintain a grip to remove the old frozen O2 sensor.
Is this o2 sensor for the 2001 jeep grand cherokee 4.0L downstream use. Bank 2 Sensor 2?
