Has Ford Not Heard of Never-Seize?

[mdavis203]

Planning to do my DPF-delete this weekend. In preparation, for about the last week or so I've sprayed all three temp probes with Liquid Wrench almost every afternoon after the exhaust has cooled off. This evening, just as a test, I grabbed my trusty 13mm Kobalt wrench and rolled the creeper under there to yank on the one behind the DPF. #@$%, that thing is in there tight! I didn't put all my weight behind it (because I need a ride to work tomorrow), but I pulled on it pretty good. It didn't even budge.

I'm thinking it might be easier just to unplug the sensors, drop the cat/dpf spool, and get them out when I'm not laying down on a creeper. But, I'm worried that I might break one of them and be up a certain creek without a paddle. I'd prefer to at least get them to move a little before pulling the spool out.

Any tips from you pros that've done this before?

I saw that stuff right next to the liquid wrench. Guess I picked the wrong one. I'll grab some tomorrow and put some on it tomorrow night, Friday night, then Saturday after I drop the exhaust. I'll let it soak an hour then give it another shot.

unplug all of the sensors, drop the exhaust to the ground..its way easier that way...i got 2 of mine off after i took the exhaust off...i still had to use heat and vice grips on one of them to break it free...

-PB Blaster is your best friend

Using heat makes me a little nervous. I've read a lot on here not to use heat on them.

Yeah, PB Blaster is great, or if you can find it, Kroil (quite a bit more expensive though and hard to find)

Hell, I'd pay $20/can if I knew it'd get those sensors loose without breaking them.
