I sure am glad I found this site right off the bat! I just got into my first Cummins in a 2001 2500 quad cab long bed automatic 4x4. Truck has 167K and started off with a few little problems (one reason i got it on the cheap arty018: ). This site helped me fixed those issues in the first 3 days. Fan blower motor/resistor switch replaced, camshaft position sensor (er was a !!), and what i originally thought was a squeaky belt and tentioner (replaced) turned out to be #6 exhaust manifold missing it's 2 bolts (fixed). Hopefully now i can dive the truck and have peace of mind for a bit! oh and i removed the silencer ring off the turbo. I'm looking into straight pipe and cold air set up and eventually a programmer. Can't wait to get back from my next deployment to toss a little cash at the beast. Parts/Mods suggestions are welcome! thanks all!
