New CRD owner-2005 Liberty Sport with 139,000 miles when I bought it on a whim. Up to 142,000 now. Wife loved her 07 Liberty gasser but I sold it out from under her several years ago. Never owned a diesel before and haven't done much mechanical work since I worked at a real gas station 35 years ago. Love the NOOB guide. My Jeep has a couple issues, cruise control doesn't work and all gauges intermittently go to zero and low fuel light comes on. Turning off and on generally fixes it but haven't figured out root cause yet. Will occasionally (twice per week) die when that happens, but generally only at idle. Anyway, changed the oil and filter(filthy and drain plug stripped-previous owner fixed with a self sealing gasket one that opens and closes by hand-will be replacing with Fumoto valve next change), replaced the fuel water separator filter (previous owner had new head installed), cleaned the MAP (unbelievably sooty), stripped all the aftermarket trailer light harness out of it, removed cleaned and applied dielectic grease to cruise control connections, instrument panel connection, and BCM (at drivers side kick panel next to fuse box?) Have had battery and alternator tested and they were good. Also, early on, disconnected the negative battery terminal for 45 minutes, cleaned up, and reconnected. Couldn't (wouldn't) have done most of those things without this guide. High gas mileage before MAP clean was 26 all highway and low was 16 all city. Average driver, not too heavy footed, and generally run 5 over the speed limit. Just cleaned the MAP tonight so will see if that makes any difference.
Sorry for the longwinded intro, but I am truly excited by this CRD!
Thank you so much to all who have contributed the how to's and the pictures. Incredibly helpful.
