Not to high jack the thread but since led lights and temperatures are being discussed, has anyone noticed the new led headlights don't generate enough heat to melt snow? My headlights, fog lights and light bar become coated in snow regularly requiring me to get out and clear them off.

I thought about rain x but I'm not sure it's safe on the plastic lenses

YOU need a road trip - ELY, Minnesota - ( temp is -25 with a wind chill -35 to -45 ,snow ) . see if your light will melt snow ????

That's what I am thinking because the light bar is in the lower portion covering one of the three large opening and if you look through the grill it was the one with the least amount of restriction 2e1379611b06ad5ec858aedd24a3ce65.jpg

yes if you get it there are like end plates screwed onto the ends of the bar and when you take them off they have a rubber gasket just make sure the gasket has silicone on the light bar side and I added a bead where the gasket meets the lens and have not gotten any leaks. Because I also purchased some of their led pod as reverse lights and they did leak so I took them apart and they did not have silicone on the gasket so I added some to them and have not leaked so far. The silicone I used was clear rtv adhesive silicone sealant I got from pep boys it's clear and waterproof

I'm not sure if this is really an issue. If the "tick" marks are correct, that means your temp is going up 12 degrees? I'd be worried if it was running closer to the red line, say 250 degrees. Then again, I don't think I've noticed mine go much above 210, even on the highway.

yeah I agree it's not heating up to the point that it's boiling over or where I need to stop the vehicle but I'm worried when I tow my project car if I am driving at a grade then I will be in trouble. Also my father has a 2015 but it's the 6.2 and I have asked him and he says he doesn't see the needle move, but I need to get behind he wheel of his truck and do some similar accelerations to be sure

Alright so I literally just joined about 5 min ago and this is my first post... I know it's a year old but I came across this while looking for info on putting a 20" bar behind the grill of my '16 CR-V.

 

Anyways, my 2012 Sierra has 6 light bars (small to medium) that are all blocking air flow and I carry around a solid 2500+lbs at all times... Never once has my temp gauge moved. 

 

I have 5 behind the grill and 1 in the bumper.

7" single row x2

7" dual row

10" dual row

12" dual row

22" dual row

 

Hopefully by now you were able to figure it all out but I really doubt some lights would be an issue unless your towing 10,000lbs in 100°+ weather or have an already weak cooling system.

      Trim level custom/pro

      Seats matter a lot.  I would start there - good advise here.  I had a 2018 LT Colorado before my 2026 LT Silverado, and the seats are so much better in the new one it's not even a contest.  That was one thing I always hated about the Colorado and I owned two of them spanning 10 years - but I did it so I could park in the garage mainly.  Now I have a much larger property and a huge barn so I have plenty of parking options and a full size is more useful for maintaining the property and current hobbies as well.  I wasn't evenb thinking about the seats as part of the reason for the move to the Silverado, but after two back to back 700mile road trips I am sold on the LT seats w/ leather 100%.  The other LT features are also nice - one thing I really like is the power rear window on the back window by the bed.  And the lighting in the bed is also very nice to have - I doubt that comes on the lower models.  Power tailgate - also quite useful - it's a heavy slug!  What else - I could take or leave the screen - but heated seats and steering wheel and cruise control on the steering wheel is very useable - I would never want to live without that.  Even the colorados had that.

      Oil Consumption

      I think the ship has sailed on the fuel injection type - everything is getting direct now.  Does it help with mpg?  Not really and nobody buying a HD truck really cares anyway.  But that is what it is at this point.  Piston rings is something they may well adjust over time to get them right.

      I don’t have detailed measurement data, but this past March we were hiking and camping in Death Valley and the Las Vegas area when this Spring’s heat wave hit with 105 plus temperatures and our 2021 L8T system kept our crew cab as cool as we wanted it (68F setting) with no trouble. Fan flows on auto once stabilized were fairly low. It seems like the OP’s system should be performing better.

      summer road trips in the 2026 2500HD

      Yes that's correct on the route to Durango - we just followed what google maps recommended.  That is quite the pass btw - very steep going back down.  I didn't even need manual mode - I just used cruise control and set the truck at 50 I think when it was a 45 posted speed and for the most part it just held it there by keeping it in the right gear - everyonce in awhile there is a sharper turn that I just braked for - but it was pretty smooth going down it on both sides.  Amazing views around there for sure - we had no real time to stop, were on the clock for a set-up time, but we did stop in some 2 horse town somewhere a couple hours oustide of Durango in the middle of nowhere for burgers.   And yes - lots up up and downs on the Durango trip but I think it's a big difference going 70 vs. going 80-83 with the aero in play with these big trucks.  Even the much smaller Colorado does reallt bad on gas going up over 70, I think I would have been lucky to get 18 on that trip in the Colorado honestly.  The full size is definately more comfy for a long road trip too, and the amount of gear we had would have meant two vehicles if I still had the Colorado.

      I'm not sure what my temps were, but it would take my 2024 about 4-5 miles of driving before my AC started cooling. They replaced my compressor under warranty.
