if i'm looking up at the bank 1 o2 sensor head first with my feet sticking out the front of the bottom of the jeep, what way do i turn the wratchet? lets say i'm laying with my feet facing south, the sensor is screwed in facing north... i thought i must push up (which would be left) correct?

also is it safe to use wd-40 on old sensor it may leave residue for the new sensor i know their sensitive
