Engine temp

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 ?

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.

When I use Torque the read out is lower than the gage.

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.

#WorthIt ???

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
