New guy with van addiction

[the_engineers]

Winter hit and I took a serious break. I finished my crossmember and carrier bearing mount and gave them to a local shop to powdercoat.


I also had a 2 pc driveshaft shortened and balanced.


After a lot of studying and a couple of failed attempts, I finally got my transmission cooler lines routed.

Starting at the trans in -10 AN.




I wanted to keep the tie-in with the radiator to keep temps up in the winter. I teed the -10 into -6 towards the radiator and -8 to a stand alone cooler.


From the radiator, I go to an auxiliary cooler.


From there, the lines combine on the return side.


Definite advantages to living in the town where Surplus Center (www.surpluscenter.com) located...

Glad to see you back on it...I took 6 weeks off on mine but dug back into it this weekend!
That cooler set up should work well for you with your seasonal extremes.

Why use high pressure hydraulic hoses for the transmission cooler lines? GM does it with quick connects and C-clips.

Why not? It’s easy to source and holds up to anything

 

[the_engineers]

The hoses are "off the shelf" from Surplus Center. I can buy assembled hoses from them for less than the cost of AN fittings. I definitely understand that they are overkill, but I'm only in them for about $12 each.

Driveshaft is in

In the spirit of "cart before horse", my 2008 PY0 center caps arrived.


I plan to strip the wheels and have them cleared again.

Can anyone ID the axle generation?
(60S, 70S, etc). It's a full-floating Dana. Not much else for identifying marks that I can find...

 

[LCAC_Man]

If it's full floating it will be a 70S(10.5" ring gear), it doesn't have the extra rib structure to be a 70HD (10.75" ring gear)

 

[the_engineers]

It's a full-floater. So is that automatically a 10.5"?

The stock lines are junk, I’ve changed mine twice in 90k miles. Just because it’s GM doesn’t mean it’s awesome.

Well, I've heard that there was some full floating 9.75" rears out there(in gas powered express/savanas) but I've yet to see/hear of one in a 3500 duramax...you can look at your RPO label on the passenger door jam and check the codes that start with an "H" and that should tell the tale. The casting bulge just above the pinion looks just like every D70 I've seen.

 

[the_engineers]

I'm a 2500. My cover has 12 bolts, so that's added to some of my confusion.

 

[LCAC_Man]

okay...that's a different story...there's a good chance that it is a D60 then...my bust...I thought you had a 3500 donor. You can for sure tell by pulling the cover and getting the part number off the ring gear...dana 50/60/70 all share a common diff cover..

 

[JoeyD]

All the duramax vans had the Dana 70s up until they switched back to the old 14bolt 10.5. I forget the year but maybe 12 or 13

 

[the_engineers]

Moved over to work on brakes. The driver's side leaked all over the e-brake pads. The passenger side e-brake lever was frozen engaged. Replaced everything from the backing plates out. New calipers on the way to replace the rotted ones...

 

[the_engineers]

Brakes are done. Also added the PPE Duramax oil pan. My list is getting shorter.

 

[LCAC_Man]

I've got one of their older versions on my motorhome trans...they are beastly..

Any updates?

Brooks (the engineers) and I email occasionally, he's been working other stuff and getting his shop set up to get back on this over the winter, as of last week he said he hadn't made any further progress on the van.
