Confirms what I suspected. Working as an engineer you realize that a lot of things aren't logical but come from practical reasons like time and money. I can see the meeting in my mind where management wants to attach the ICM to the engine block and all the engineers start muttering swears under their breath.

So, Scrappy, are you close to 10K miles yet? There's interest in your mod again, so I wanted to ventilate this thread a bit.
Anyone else give it a try?
DrCook - We're actually discussing this mod in another thread, so it's not a true zombie.
DR = David R, most just call me Dave. The zombie threads were accidents. Not on purpose. Solely because folks got drug into and accidently posted on an old thread by the software features :-) Don't make it into anything that it wasn't.
For the record, I read the old threads that are brought back on purpose. New discoveries, new knowledge, new techniques are learned when it was brought back for a reason.
Earlier in the thread it was mentioned about mounting the ICM to a plate before moving it. With that thought in mind, you can purchase additional heatsinks, from places such as this:
last summer my tuner suggested that i relocate my icm and coil to a cooler pace, which i did. i mounted it to a piece of aluminum and then mounted that to my cross bar, right behind the radiator fans. when they come on, the airflow is great and no engine heat to soak up.

and add them to the aluminum plate, making it much more effective.
this is a mod I am actually going to look into
Boy....and all this time I thought you were a Dr....
I know way back in the day when I was a mechanic, we moved a number of things off the block or heads. Modules, coils, whatever vibration and heat may effect, if the design would allow. We always figured the builders jammed it all together for assembly purposes.
It all goes back in time to when I worked in Goodyear Aerospace's defense plant. My security badge said "DR Cook" of course. That got me lots of laughs.
Another friend name was Richard A Novak. When he put his name in computer programs as the author, of course he put it a:
Ranovak
That reads very computerish.
GM had an issue with a controller on their prior gen diesels. (prior to the Duramax). They mounted a critical component where it would get heat soaked and fail long before its design life. The fix was to move it. That was all it took and then they started lasting as long as they should have. In the Duramax's, the 2nd'ary battery is mounted in the passenger side rear of the engine compartment. At least up through the 2006's (after that I have no direct knowledge) due to the way the fan spun, the heat would concentrate in the right rear and shorten the life of that battery. I put functional hood vents in my fenders and you can feel the air being forced out. As a test, I fastened some teflon tape to the vents. The tape on the right rear would blow out horizontal at idle from the released pressure. This mod also helped with the overheating issue that was designed into the truck.

where can I read more about this? I just replaced the batteries in my duramax for the second time last summer. They were just about 5 years old, so I guess I got my money out of them.
I used nylon washers under the aluminum heat sink to the steel bracket and also on bracket to head. I can't recall, but used studs to mount the bracket as something else uses it, I think power steering ??? To cold to go look!

It was touched on over on the Duramax forums. No one ever could pin anything down, but if you feel that back right hand side battery after driving for a while, you will find that area is quite hot. My vents also help with my intake air temps. Once I start moving, the IAT's drop to outside air temps because I have an 06 air intake retrofitted to my truck and it pulls from inside the fender.
The vents are not specifically made for this, it was an adaption. If you are interested about this or the forums, we can take this off the forum and talk about it. If you want, PM me your email address.
Are these ICMs known to fail? I mean, is this a real issue? Did I miss the memo?
Never heard of any significant problems here, although the relocation is probably a good idea anyway (if done properly).

How significant a problem do you need to consider a simple mod?
The peeling Dulso on the console isn't an issue that will strand you like a dead ICM, but there are plenty of threads describing how to fix it.
