i would, chances are it wont fit, iirc the say bar is at the end of the sensor. i got a socket on mine but it got stuck on the bar. then had a wrench that fit but you only get 1/8 of a turn, so out came the channel locks, and off it came in seconds. i was surprised to hear Bill suggest channel locks as well to deal with it.

oh. big tip, have a small pan under the sensor, to catch the oil that will pour out, a 1/4 quart maybe.
