I just got my build sheet from the "[email protected]" folks. Very friendly! 

 

I have VTI on my 5.3L DFM RST. Didn't realize that! 

I sent an email to the address you shared and got my build sheet in couple of hours. Thank you very much for sharing.

Surprisingly, my truck has VTI code too, but the QR code doesn't list it. ?

Now I'm purely confused with the temp. The only thing I can see is different thermostats for the same engines, or some defects in my engine, since it runs in low temperatures at all times ?

My 2015 always showed 210 F. I removed the 207 thermostat and installed a 180 F. Still reads 210 F.

I think we tried to pattern what trucks got them in a thread a few months ago and I never made any sense out of it. My 6.2 doesn’t have them. Thought it was because of NHT but then someone else with a

Shutters were not part of the deal when I bought my 2015 and I wish they would have been. Open they do not inhibit air flow. Closed they speed up heat up. Pretty nice feature if you consider the oil is heated in the radiator during cold starts. IMHO anyway. I have need to tape my grill in the middle of Midwest winters to do the same job the shutters would do automatically. No one make a canvas grill cover for gas motored 1500 that I have found. Doing so has been good for about 3 mpg in the winter months and hurts nothing that I can tell.

My LTZ 5.3 DFM is so low. may be around 180 and lower most of the time. In the past 6800 miles I barely saw 200. I'm not towing any load. 

Mine has been the exact same way. I just picked up my Silverado last week an noticed it runs cooler than my 2014 and takes longer to warm up. I also noticed the oil pressure tends to run higher until the engine warms up a bit as well, around 500-600kpa which is around 72-90 psi. Not sure if that's just coincidence though.

I would bet money the analog gauges are not a "true" gauge,  whereas the digital gauges show the actual temperature. 

 

I've seen analog's in the past that basically have a "low", "at operating temp" and "high" movement of the needle with nothing really in between.  When the needle is actually put on the cluster if it's not perfectly lined up it could be left or right of the 210 a smidge.  Mine reads a hair over all the time once it's warmed up.

 

Just a thought- pure speculation based on past experience.  :)

This has been my experience.  My Jeep Wrangler analog gauge needle never moves, but my digital temperature readout fluctuates between 202° and 226°, when the electric fan kicks in.  I wish my Silverado could display temp and oil pressure in digital format.  At least I can check the transmission temp.

My GMC Sierra was heating up driving up on hills. The issues was that the radiator cap was wore out. It will pollute the coolant. Flush the coolant and buy a new cap as your first option. Also I had to do an oil change since this engine heating will burn your oil.

My 2020 silverado came with a one row radiator 5.3 litter ........ I find it kind of odd ...... it runs at 210 all the time even with a 180 T stat. I put on. 

Some ******'d up design.  My 2017 Cam was always at 160 +\-  I ran the VIN and seen the assembly plant is in Indiana and I live in S. Texas. could the truck been assembled for cold weather. because S. Texas heat and 210 degree seems rather hot and the rad hoses swell up. PROBOBAL SOLUTION; LOOKING FOR A 3 ROW RADIATOR AND GONNA FIND SOMEONE TO  REPROGRAM THE PCM ==FANS

Anyone else running just a touch over 210? My 2015 5.3 never did. Running a 2019 5.3 DFM. Seems to hover around 210-215 and that's without a heavy load or anything. Not too worried about it, just curious to see if everyone else has the same.

I bought a pre owned 2020 LT   5.3 ( 62,000 miles ) I noticed the T gauge is steady at 210 I looked under the hood and seen a one row radiator. I swapped the T stat to a 180 but goes to 210 anyway Maybe the radiator is the one causing this issue. S. Texas is always hot... I wish the engine temp was cooler. hoses are swollen and ballooned , gotta resolve this

      Looking at ordering a '26 WT because I want a std cab, std bed

      By newdude · Posted

      So.  Get this.  On the Chevy regular cab, you can get the factory remote start at the dealer from the accessories catalog.  BUT.  GMC, you can't.   Now...get this...GMC 2 door, you CAN get the power seat.     Go.  Figure.   Anywho.  are you trying to order?  Or locate?  Ordering for 2 door 1/2 tons has been stopped as of April or May?  So you won't be able to order.  You'll have to shop on the ground units or in transit units.     Ordering was stopped because the new trucks are coming.

      Tonneau cover that does not leak water

      By cherryred21duramax · Posted

      Thank you.  I really appreciate the well wishes.  I'm an engineer in the telecom industry, I know hardly anything about marketing.  Over the years I did some videos for nonprofits and web sites for small businesses and the seed was planted.  Agree with over-buying, I started shooting on an iPhone before I got my first DSLR and tripod.   I'm looking at trucks with potentially 150,000+ miles to keep the cost of entry low while focusing on the client experience and equipment.  Good wireless mics for interviews, the right lenses & lighting to look professional.  But I don't want to be late or break down, the stress of emptying a trailer & securing a rental truck right before a gig would negate any savings from buying a junker.  So anything that leaks water, has extensive rust, or generally unreliable I'd like to avoid.   Does GM/Chevy overbuild these trucks for upfitting?  I talked to a local upfitter, they sometimes tie lights & other 12V into existing circuits, which I always thought was bad.  Which is why I enjoyed the AUX upfit switches on previous trucks (odd they mostly come with off-road or work truck packages).

      injector cleaner 2021 2.7 1500 silverado

      By silveradosid · Posted

      i guess it might be depending on the type of driving. my 2.7 has 120k miles, changed the plugs at 70k and it runs as good as new. i have not used any injector cleaner

      GM's are stainless and have a fairly robust powder coating, although, still not worth $850 in my opinion. They will hold up a lot better than their cheaper steel aftermarket counterparts.   What I like about the GM step bars is dealers will often equip their dealer stock with them. Lots of margin. Which means a lot of people end up buying them because they're already on the truck, even if they don't like them. So it's pretty easy to find brand new takeoffs with hardware on Marketplace and Craigslist for about $250.   That's what I did for my crew cab. I wanted ZR2 rock rails for the look, but with the ability to bolt up GM's assist step package. From GM it's about a $2500 accessory all in. The old folks in my life can't get in the truck without steps. I found the whole package on marketplace for $180.

      Forward collision and lane keep assist still a problem on 2022 refresh?

      By kr477 · Posted

      I am really glad I found this post and this site... We have a 2022 1500 refresh LTZ that has these problems: - forward collision avoidance warning light - lane keep assist unavailable - adaptive cruise control unavailable   The truck was bought as a new leftover in 2023, so it was still under the 3/36 B to B when it went in for these problems earlier this year. It has been at the dealer on and off now for about 110 days now. These are some of the things they have done that I can read on the service tickets. - replace/add ground straps (4) - check all battery cables and vlts - replace serial data gateway module - replace front view camera - numerous reprogramming - a few calibrations (apparently ending with 'learned') Last week when I had it back the truck had those 3 warnings every time we used it except for 3 times. On three separate occasions the truck started and ran perfectly with no (zero) warning messages or warning lights lit - everything worked perfectly. Over that same time period the truck did not work on every other 'key' cycle which I would estimate at 60+ cycles. On those estimated 57 cycles it had the same 3 problems each and every time.   It is back at the dealer now - can anyone help at all with what the true problem might be?  Or possibly what can be ruled out leaving a lower number of possibilities? Thank you very much for any help you may be able to supply....
