Blatant

Hi Gang, 2021 2500 4wd no oil use no coolant use 16k I realize this may be a dimwitted question, but the manual makes it way sound more "complicated" than any other vehicles i've owned in the past. Trucks or bikes. I have NO low coolant light, but as i check levels routinely, i see i should add a touch to get coolant up to the seam. Can i just mix it and pour it in to the firewall coolant tank? Is there really a "leave the cap off, run the truck to temp, yada process etc" that needs to be adhered too? Again, gas engine, 6.6L8. Can i not just top it off? And for all those that say "just follow manual" [ which i don't disagree with ] thanks but still, insight would be appreciated and thanks folks.

is it safe to assume if you have the time added gmpp or the newer variant, platinum as example, you would be covered as well?

Thanks JR. So you had that fuse / wireblock off? How do you get it off? Is there a bolt? Mine looks just like that. I pulled the top off with the two tabs and it revealed exactly what you show above. I can grab that wire cover and it seems loosely mounted, like by a bolt somewhere. As it does move but it sturdy. Does anyone know what needs to happen with that "wire block" on top of the battery?? Proper way to remove? Is there a timing thing being without the battery and these trucks? Can the truck be without power for an hour or two while getting battery with no bad effects? Some vehicles like vw can't be without power. Thanks again everyone.

Thanks @Pryme, appreciate it. Must've been others that have swapped the battery by now. Figured I'd grab an AGM. Anyone else with feed back? Anything to be wary of? Or is it just a simple swaparoo? Likely over thinking it.

Is there any complicated issues replacing the battery? Hopefully not a dumbass question but is there anything complicated or different with the GM 6.6gas battery about swapping the battery? In other vehicles, where its in front, with two posts, and no "cover" it's a 10mm and 5 minutes. This gasser is tucked in back and has a shroud over it. YouTube on the 1500's look awful, involved and hassel some, with all sorts of wires to disconnect etc. Any tricks, tips ect with the 6.6gas? Just trying to understand ahead of time. Thanks for the feedback.

I have one, fits great. Nice option if you're not really throwing alot of nasty stuff in back. if so, it'd stick with bed liner and thick rubber mat.

please, more info, inks, etc? The rear defroster is linked to the heated mirrors I think. How is it exploding, from the heat? The solid rear window or the window with the slider?

^^^^ QTF. Even this GM forum is budget...fck.

stupid gm can'ed response, if it's even GM. ^^^^^ @Epsilon Plus east valley here. Let me know how you make out and the dealer you take it to OR if you reached out to the GM genie listed above and your result. Mine isn't bad, it's just not right and certainly not normal, imo, despite what is said, tsb's say etc. The fact folks have been talking about this for years / decade, sorta make it normal...crying ass shame. All that said for longevity, these trucks are not toyota land cruisers, they are not going to get 300k on oem. It would be nice but is wishful thinking imo.

Thanks. @gemarsh or anyone, what about the following? See these mentioned as utilized fuses on the 2020+ 2500/3500's...thoughts? Micro 2 an Micro 3 https://www.amazon.com/gp/product/B01N16GVY4/ref=ewc_pr_img_1?smid=ATVPDKIKX0DER&psc=1

@JFroh81 where do you live in the us / canada?

bumping this back up. What fuses do we need? 2500 gas, 2021. The manual is not clear and doesn't specify types, or i missed it. It doesn't tell you. I would like to get a fuse "kit" as i travel a lot. Hard to find info on what is needed, unfortunately. any help is appreciated.

so it was just residual oil drip from the change?

i've used tow haul on super long down hills from time to time, not towing, to keep the truck holding gear, rather than messing with the manual shift.

What is "the recall" and what are lower shutters? Thanks for the info.
