Gave up again. At least I am at the point where I got a mirror and can see the hole and sensor in the hole. Taking off the valve cover helped gettin gin there. This thing is in the hole and will not start. I made up a tool so I can see it when i get it down there out of heater hose that goes over the sensor connector and a flex drive.

 

I did notice the new sensor was a little tighter than the one I took out. I have a brass adapter for some gauges and the old one and the new ones screws in fine. The new one is a little tighter and has a smaller angle on the nose. I am ready to buy a new one from a different manufacturer to see if i can get it in maybe the threads are off a little. This is crazy! I have pulled many motors and all kinds of other car stuff over the last 35 years this one takes the cake.

Im finally to the point where I am trying to replace it. I cant even reach it all so far. I can reach the crankshaft sensor, but thats it so far. This is a terrible design. Has anyone replaced it with the valvecover on? So far all I have taken off is the drivers side coil pack.

Well, I finished, and it was a bit aggrivating. I found that if I remove the rear coil pack on the drivers side, and lay across the engine with my head angled towards the passenger side, I can reach it. I used a 27MM socket and it fit perfect, once I got he socket on, I used a couple of extensions(Wobble) and managed to get it out. The new one was tricky getting to start, I tried for about an hour with my hand. But no luck. So I took a 6" piece of heater hose(It fit perfect) slid it over the connector, that gave me the leverage to get it started. From there it was just a matter of finding the right extension combo to run it down. Also, reinstalling the wire was fun too:) But my gauge works again, thankfully.

      I will be one of those "blinded". One, I like new shiny things. Two, I've never kept any of them beyond the 3/36. Three, I don't finance anything. Four, yep, it's a waste of money....so,what? I'm doing my part of keeping automotive industry going and keeping my neighbors, most of whom are in it, employed. 😉      By the way this is the "signature... ¬

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By marpel · Posted

      Although there is a "recommended" weight by those who sell trailers, my experience has been that they are way too aggressive in their information, for me at least. My '22 with 6.6 Gas, has a payload of about 3400 lbs and depending on your specs (I don't have 4WD so it has a bit higher Payload than others) yours will likely be different. Payload is one of the most important numbers for towing. Although you "could" tow the max trailer weight for your truck, I, personally, would not go close to that number. Having said that, a lot depends on how/where you will be towing. I live in the LMD of BC and often tow to Denver, Co, along interstates (flat and mountains) and I find I need to keep it in 5th (6spd) for the trip and travel at around 65mph. This is for a trailer dry weight of just under 3500lbs. If you are only doing local, short trips, it would not be that big an issue if you had a heavier unit. You will be surprised how much stuff you load the trailer with, so I would only recognize the trailers "full" GVWR weight rating, then decide on the appropriate trailer from that number. If you are worrying about how much stuff you should be putting in a trailer, you might have too large a rig from the get-go. Once again, depending on what terrain/distance in which you will be pulling. Marv

      Disconnecting Battery

      By marpel · Posted

      davester, Thanks for the response, how ever, I think I am now a bit more confused than I was before I posted - - After I posted, I actually found a YT video of a guy who replaced his Module (above tire) and he only disconnected the ground cable of the battery, but you describe rubbing the two cables together after disconnecting. I presume that is to do as you describe and eliminate any residual energy? - When I picked up the Module (between my posting and reading your response) from the dealer, I specifically asked about any re-programming and he stated it was not necessary as it was simply plug and play. Don't know how knowledgeable he is, though. - The video I watched also showed the Module plug to be difficult to "unlock" and remove, but there was no mention of silicone, although the video did show a bunch of dust/dirt in and around the plug (old truck) during removal. Are you talking about silicone that was applied by the factory, or silicone that you applied prior to plugging in? Thanks again, Marv
