Has anyone ever tried changing the aluminum line to rubber hose crimps for the transmission and oil cooler lines out for AN fittings on and 07-13 Sierra 5.3L? I have a 2013 Sierra and the cold here in Canada isn’t kind to these crimps as I believe the rubber and aluminum have different shrink rates because of difference in material causing them to leak. Replacing them will not solve the problem as the will just do the same thing every year. So what I want to know is if anyone has successfully done this and what fittings did you use?
Ok guys (and gals),
I am very likely in need of a second "loaded" work truck this year. Having been a Cummins guy for the last 22 years but since 2017 an owner of a Yukon and as well now a Camaro the way the new GM product is spec'd it has all the bells and whistles but still functions like a truck, minus the solid front axle. Having tested a new 2021 3500 AT4 DMAX - I really like it. I love the upfitter switches, the HUD and the ride is as good or better than my 2012 3500 RAM (which has aftermarket FOX 2.0 shocks and a nice lift). Now for what I do, it still needs to be leveled out as that front lower valance will get ripped off in a week but otherwise, very nice.
Comparing to a similarly equipped 3500 RAM and honestly, and this is coming from a RAM guy, these aren't even in the same park, let alone field. Sure the Cummins is great but the truck felt a tad cheap and when both are over $100K (CDN) it has to feel right. The other big gripe I have is with that 12" screen. I love tech but if you just want to turn on the seats or something, there are too many screens, too much distraction and frankly as I do a lot of driving at night, even turned down it was too bright and made it hard to see outside.
So for this knowledgeable group here are some questions:
1. cost of ownership? this will be a work truck and not a grocery getter so it will do a lot of long hauls but more so, a lot of slow bumpy driving on goat trails. So is the drive line up to the task? I don't want to be getting alignments every other oil change or whatever.
2. V8 DMAX vs I6 Cummins - again cost of ownership? will I get 400,000 km before I need to do anything major with valves, rings etc.?
3. I do a lot of idling (no comments from the greens please) so this must be able to handle that without burning a bunch of fuel (or something might just fall off). EGR? DPF? DEF?
4. I wasn't planning on a shorter than 8 FT box but I really don't need another "barn on wheels" so is this "standard box" good enough?
5. GM 10 speed auto vs the RAM 6 speed auto? The RAM is not all that great but I know how to fix it.
Now to throw a wrench in here, I started looking at the 1500 AT4 but quickly found no upfitter switches and it needed a 4" lift kit even though it claims to be taller than a regular sierra - although frankly, that is marginal at best. I though the 6.2L would do me fine with the 10 speed auto but I am concerned about my 10 year 400,000 range I typically consider for replacement but equally thought that I could add a 2.7L super charger to it after the jobs and make my own version of a Hennessy - because I think I could do that.
So, thoughts? comments? am I crazy? remember, work truck, long distances, lots of idling and so on...
Any help would be greatly appreciated.
Has anyone used this PSI Power Tuner or found where others have used this? I found the product on two different sites; the 2nd URL has better details on the product. I'm skeptical on this product, being that no other tuners have released products for the 3.0L Duramax (LM2).
PSI Power 2020 3.0L Duramax Performance Module (Truck Edition) | Thoroughbred Diesel
Agricultural Diesel PSI Power Module 2020 3.0L GM Duramax (parleysdieselperformance.com)
Also, what about these two products?
