I was finishing up, putting brackets back on the '09 today and ran into a issue with the passenger side lower alternator bracket. When I went to slide it on the studs it hit the water pump housing. Enough that it was a real issue. This was a brand new AC-Delco pump purchased at the GM dealer. I...

I was installing the water pump today and followed the TM to the letter. It occurred to me...after I was done and had torqued everything of course that the TM only specifies pipe sealant on 1 stud that threads into the head below the water jacket on the drivers side as well as the 4 bolts and 2...

do I get the nut back on for the driver's side stud on the injector pump? I was only able to get it off by breaking it loose with a open end wrench and then after using a ample amount of PB Blaster...using the tip of a screwdriver to spin it off by pushing on the edge of the nut. Once it came...

So I continue on my big reseal project. I have learned much on the journey...LOL. I'm sure many of you have done this kind of work before but for me it's been many years since I have decided to take on such a task. They always seem so easy in my head...LOL. It's nice to have friends that work...

Please alleviate my paranoia...had a *ell day... So I had a really difficult and frustrating situation develop today during my big reseal extravaganza... Everything started off great. Damper came right off last night. No problems getting water pump as well as the timing cover off. I have no...

My girlfriend picked this up for me when she heard me talking about all the work I was going to be doing. It's a Kent-Moore J-22102 Seal installer / timing cover aligner whatever that means. She picked up a used one that is basically new for next to nothing so why not?...:) I love tools...

So I started the big tear down today. I have set aside a few days to do the work. I will be fixing some leaks as well as replacing the water pump and installing a new Fluidyne damper. The radiator will hopefully get re-cored if possible. If it can't be re-cored then I will have to bite the...

Is it OK to re-use the timing sprocket bolt that goes thru the IP gear and timing sprocket into the camshaft? I picked a new one up at GM for a possible timing gear swap but after checking the bolt it was determined that it's Chinese made...:mad: I got a new washer as well which is US made but...

Crankshaft key replacement with balancer swap? Hey all, So I'm getting ready to pull the timing cover off this weekend to fix a coolant leak as well as replace the water pump and the harmonic balancer. What seems to be the guideline on replacing the key on the crank? Does the key need to be...

What color were the engines when they were installed into the M1009's new at GM? Curious...Thanks!

I recently have run across a Stanadyne pump DB2829-4521. I know this is for the CUCV's. The pump is still sealed in a big foil bag and boxed. All the NSN numbers, Model numbers etc. are on the box and it feels like the pump is bolted to a plywood board inside the foil bag. Were new injector...

Is the governor assembly used in the M1009 TH400's just a standard governor assembly? If so anyone familiar with the Sonnax units? Thanks....!

Hey all, Can the later timing cover from a HMMWV with the crank trigger pickup be used on a M1009? The only difference I think I see is that the later cover has the mounting boss/hole for the crankshaft pickup on the drivers side behind the timing indicator bracket. If one needed to replace...

So I was under the truck today checking on some items and found a coolant leak that has me dreading things to come. I kept finding coolant at the very front of the oil pan which had me puzzled as to where it was coming from. I decided to get the super duper Surefire flashlight out and start the...

I was underneath the truck this morning and decided to take a really good look at the harmonic damper. I noticed that I have some cracking of the rubber visible on the back side with a couple of very small thin pieces missing. On the front I don't see any bulging of the rubber anywhere...

Ok...so I went out to start the the CUCV at 3am this morning to head in for my flight shift. I'm in Southern California and it never really gets very cold but this morning it was 35 degrees. I fired it up and as usual it started instantly. However lately I have been noticing that on cold...

Can someone suggest the easiest way to replace the dipstick tube seal in the trans? I read the TM and I know it's a simple job on the trans end but how do you get at that bracket bolt the holds the dipstick and vacuum hard line to the bell housing? Is there a trick to getting at that bolt? Thanks!

I'm throwing in a coolant filter to help get rid of all the junk in my system. I flushed it several times today and sediment still is visible so it can't hurt..:) I just want to verify that the filter feed line IN should tap into the heater hose for the "block to heater core" line and the...

Does anyone happen to have a pic of the socket guts for the Volt gauge? As I was tracing down non-functioning dash lights today I discovered that the grey wire for the Volt gauge light socket was ripped out of the back of the plastic socket and the wire was hanging down behind the dash taped...

So I was putting in a new thermostat today. I picked up a Napa unit(which they had to order) which is made by Stant and was really pissed when I got it home, pulled it out of the box and saw it was made in China...:mad: So does anyone know what brand of thermostats are still made in the good...
