Title: Removing seized temp sensor?
Post by: IAmCanadian on September 22, 2011, 09:14:22 PM: Hey guys,

I have a 5.9 cummins engine, and my engine temp gauge is bad. I believe the easiest way to fix this is to just get a new gauge and sensor (about $70). The problem is I can not for the life of me get the old sensor out. It is just totally seized. I am not stripping it or anything, it just will not move. Have any of you had any experience with this and have tips for this? I have already sprayed a ton of penetrating lubricant, but it doesn't seem to be making a difference.

Any thoughts on this would be great!

John

If you can get your impact driver on it no hammer and wrench required.

Almost sounds like a hint from Heloise ;D ;D I'll have to remember this.

Its a newspaper the has stories mostly about the ingenuity of farmers and how they built snowplows out of combines, unfreeze frozen bolts, build their own "everything" from stuff laying around the farm. Some of it is pretty "rube goldberg" but a lot is pretty cool stuff. Lots of good tips and ideas like the wax on a bolt.
