Sorry to hear the sad story. Mine was not easy by any means but fortunately I had the right tools for the job. Cannot recall for sure now which bolt was which but one was a "cap nut" type bolt, probably the top for the bat cable and one below, as you mentioned was at an angle so I had to cobble together something for that. And of course the bolt heads are all different so I had half the garage out there including deep and shallow sockets before finishing. Metric of course. If you did not have one I found six point sockets worked the best on the hard to access bolts. 12 point tend to slip. I am surprised the impact didn't work. The snap torque of an impact is amazing. My tool is a Milwaukee impact with something in the neighborhood of 450 ft lbs of torque. Amazing tool. I guess you can add this to the loss column and I hope the win column is much better. Maybe the Cummins Gorilla tightened this bolt too.
I did not have an issue with the oil filter being in the way but can't hurt since you will be there anyway. I used an end wrench on the sensor even though I have the socket you mention since it's a tight spot for a socket. Once broken loose it twisted out pretty easily. But....there is always a but....I had to free up the long pigtail to the module so the "tail" would unwind. I rerouted the lead different than the assembly plant to make it easier to remove if needed. And it was needed as the first one failed. Guess you could also cut it but you have to remove it anyway.
Mike, you are right. You have to take the bracket off in order to get to the rear little bolt that holds the sensor to the bracket. The bolt that I could not get out was the bottom one that holds the bracket onto the engine. To make matters worse, this is a combination bolt/stud that ground wires hook onto. So you take the nut off the stud part of the bolt to get the ground wires off, and then pull the bolt/stud out without damaging the stud.
The module that I had bought was from Redline Products and there was no core charge. Somebody else said that the sensor could be cleaned with carb cleaner. I did that but it didn't work.

Late to the party here, but found the attached directions.
You can always try again.
I don't know the name of the cover where your tools are, but if you need directions on that and know the name I can look.
I'm busy tomorrow but will take a look when time permits in case you need something else.
Even for the pros says level B 1.1hr on this one.

For sure you can reuse the original bracket. I was surprised when it came with one. That lower bolt was a problem for me as well but came loose for me. The sensor, as you know, is near the fender well or maybe it's the firewall at an angle which made it a little awkward to get a wrench or socket on it. I have a shorter version 7/8 end wrench but still had to angle it in place. If I recall I was able to tap the end of the wrench with a hammer to snap it loose then it twisted out easily. The second time it only needed a little tug on the wrench. I did leave about a pint of blood behind on the first go around but the second time went better. The way the wiring was routed made it difficult to get to the wire ties and then the insulation also got in the way. The second time was much easier.
Would it be a good idea to blast the bolts with Kroil and let set overnight?
That certainly wouldn't hurt a think , I am sure going to find out here in the next couple weeks ,need this taken care of. Thanks.
