Upstream o2 sensor
Any tips on removing/replacing the upstream 02 sensor? It's a 1997 Country and the thing looks like its very rusted-in.
Do it when its hot? Do it when its not? PB blast it?
Thanks for any info....

Soak it down for a couple of days with PB Blaster and try removing it when it's at normal operating temp. Just don't burn yourself.

My 12" wrench and everything I had couldn't budge mine after a week of pb blast. Borrowed an o2 sensor tool from autozone, worked like a charm. That thing was in there good.

A "free" comfortable hand tool socket that fits over the sensor perfect without risk of rounding it off worked good enough. If I had access to a high temp torch that would have been more fun probably...
