Okay... I've just came from underneath my car trying to replace the rear Oxygen sensor. These bad boys are in there. The sensors are the original ones from 1997 & they've seen plenty of Chicago weather. I don't want to use a torch so the mechanic says $50.00 for him to bust them loose.
I'm currently using Kroil penetrating oil, since about 11 am cdt, now it's three(3)hours later and still will no move. Quick questons.
1) How long does this stuff need to be effective?
2) Should I keep spraying them down every 2hrs or so?
Forgot to mention that the O2 sensor are between the cats, so they see winters and all kinds of weather directly on them.
