Pics and info 2017 2500 Duramax


Recommended Posts

Finally got a chance to look at the underneath of my new 2500 duramax that I picked up this week. I love it so far, but there is a cooler of some sort, looks like it may be for the Allison - mounted just in front of the fuel tank, and no skid plate or guard around it. Sure hope it doesn't become a victim. I ordered it with the skid plates and everything else has them but this little gem. Driveshaft and U-Joint's definately look heavier.

And that DEF tank is one ugly MF'r.... May have to get the Power step XL just to hide that thing.... I am selling the factory steps (had them just keep them in the box and not install them).

The dark slate metallic looks better in person than the GM website, imo

That cooler is a fuel cooler. All Diesel trucks have had them since the LBZ engine (I can't remember if the LB7/LLY had them). It cools the fuel returning to the tank.

LML didn't have the fuel cooler. Can't recall about the LMM.

 

But the mounting location was still there.

How is the dark slate compared to irridium, do you have any idea? If I were to get new, it'd probably be dark slate, but I have yet to find one in person to compare

Can't help with a side-by side, but pics are starting to show up.

Yes fuel cooler. LB7, LLY, LBZ and LMM had one. LML did/does not. L5P does again. All the G vans with all 6.6 Duramax (LB7, LLY, LBZ, LMM and LGH) have a fuel cooler.

FYI. Had ordered AMP Power boards for my 2017 GMC 3500 Duramax. Truck FINALLY showed up and lo and behold the new LARGE, DID I MENTION HUGE, DEF tank is so large that the AMP Power boards will not fit it. AMP is now at the drawing board redesigning their board. Nice.......

Interesting and glad I didn't oder last week when I called them... I specifically told them it was a 2017 and the DEF tank was bigger, I was told that they had already addressed it and was given the part number 75146 (which oddly enough is the same one that Bestop uses too. I wonder if the XL power step would hide that thing better.

Thanks for the info about it being a fuel cooler.... Seems odd there is no guard around it.... I really like the 5 spoke wheels on the truck in the Dmax forum... Tried to order those on mine but was not able to get them/not avail. Also can't believe they still can't put an Led in the glove box yet... lol

 

I also like the Dark Slate better than the iridium.... just my .02..... If they didn't have the dark slate I would've prob got Iridium though.... I will say that the Dark slate looks better in person than on GMC's website..

Shagmax - just saw this. Let me know if they work so I can try a set. I have the AMP Power boards on my 2015 and like them but since AMP won't work....... Thanks!

I'll try to post a photo from AMP's website.. I emailed them this morning to inquire about how far down it hangs... From the photo it looks like in the stowed position that it might hide a good portion of the tank.... The XL boards are pricey though.... Wish there was a DEF tank relocation kit...
