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

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
