Forgot to add vehicle details - my apologies! M1009 with stock GM 10 bolts. Just checked out wfo and diy4x. Look like bombtastic covers - for DANA axles and GM14 bolts. No 10 bolt covers :cry:

Howdy Folks! Both front and rear diff covers are pissing fluid. Just replaced fluid not too long ago in both axles, smeared a very liberal coating of RTV to seal things up. Apparently that didn't quite work. The rear diff cover is peeling rearwards at the bottom (draggin on something on the...

'Dependable' indicates there may be more than one switch to troubleshoot. I was troubleshooting Cold Advance Switch: 2 PAOZZ 11862 14071047 SWITCH,COLD ADVANCE 1 As seen in on figure 54 on page 54-1 of TM 9-2320-289-34P (The intermediate parts manual). I replaced this switch (and tested both...

Welp Howdy Guys - I see the PNK/BLK-39A / PNK/BLK-39B splice on E-4 (All except M1010) of the -34TM. I must be failing to spot the temp sensor 'dependable' is referring to. Can someone please help me find this in the wiring diagrams, and maybe a quick description where this is found on the...

Howdy Folks - The big green turd has been quite the SOB to start lately. There is no voltage at the cold advance or fast idle leads that connect to the injection pump. I have replaced the thermo-swtich at the rear of the passenger's side of the block that threads into the block that governs...

Mistaken - Thank you so much for the helpful replies. I will add some quick responses, then I'm off on business :( I must check if I am indeed getting power to the fuse. Didn't actually check this. Yes, the block calls for a 20A. A 30A is in it's place. the green wire at my IP has two...

Mistaken - Thank you so much for your help. I'll get to the bottom of this sooner or later. A few quick results: The fuse that controls the temp sensors has a 30A fuse in the fuse receptor. It is good. Went to the truck (that has not been ran today), turned the ignition on run, and...

Mistaken - I do indeed have the manuals. Thanks for posting the link. I did read up again on the GP Module Theory of Operation thread. I don't believe this controller card controls the cold advance in the injection pump. Under the dash, I do see two printed circuit boards (PCBs). One by...

Hm, very interesting. I can definitely buy that. Any suggestions how to troubleshoot the cold advance solenoid? I am uncertain how the voltage is applied to the cold advance solenoid. I have some pictures of the injector pump below. 2 spades are connected to the IP, one red/pink for the...

Howdy Folks! This may take some wind to fully describe how my M1009 is behaving after this weekend's work. I will try to be concise as possible. Here is the situation: Problem: While engine is cold, up to 60 seconds after startup, and a modest blip of the throttle (50% or greater) the...

Explanation of the photos: Photo.jpg - connection of hoses 8 and 5 on page 3-59 TM-20 Photo (1).jpg - picture of engine bay coating in oil (presumably diesel) Photo(2).jpg - picture of frontmost injector, passenger side. Frontmost drainback line was extended to reach over the AC bracket. This...

TM 9-2320-289-20 3-18. FUEL DRAINBACK HOSES REPLACEMENT. Came to work today and luckily the pavement was went. Backed into a parking spot and found a fair bit of oil on the wet parking lot. Opened the hood and there was something leaking fairly substantially on the passenger side of the...

Well I called up Chris from OffRoadDesign and had a very educational chat with him. He was suggesting still to place a 4" tuff lift with EZride springs under it. He reckoned they wouldn't sag even with the 6.2. Guess he as an M1008 that he's done quite a lot to (including cummins swap, yeah...

Third - Thanks for the suggestion of BDS. Are you running this kit currently? Are you able to comment on the ride harshness and articulation ability/limits? AJM - I appreciate your feedback. Are you able to substantiate your claim against Skyjacker and ProComp lift kits?

Howdy Folks - Fixing to lift the M1009 here soon. I've been scoping out the lift kits, talked to a few folks in town and gathered a few opinions. Just looking for a simple 4" lift kit. I don't want to modify the drivetrain too much (at this point at least), dealing with longer driveshafts...

Glad to see you finally solved your predicament as well. This is my story for the solution that worked for me. Oil cooler lines were too large in diameter, by 0.010 or so. Slept on this for a few nights decided what to do. One morning before work (it was chilly, well for Tucson standards...

Howdy Folks - I'm curious if anyone knows fan shroud interchangeability for the m1009 between the gasoline C/K series. My m1009 came with no fan shroud. As summer is ramping here in Tucson, I'm expecting the triple digit heat to come for the long haul soon. Anyways, curious what shroud...

Mark, what was your solution to this problem? Just encountered the exact same problem, replaced radiator and engine oil cooler lines don't fit. Reference the thread I just posted for additional details. I am quite interested how you solved this!

Howdy Folks - Condensed story: Radiator had a small leak from previous owner, leak got worse, took radiator into radiator shop to evaluate it's condition. Report was most tubes where soldered to the header plate were leaking, both header plates required a rebuild, re-soldering most passages...
