Quick summary, New 3 core rad, Dual electric fans(both are working) 160 t-stat, Would not get over 200 degrees in 103 heat. Now the last 2 days only 99 degrees but the truck will get to the high side of 210 setting at idle. water pump seems to work fine also if I'm getting flow to the upper rad hose it means the t-stat is working right? I also have about 30/70 anti/water mix Like I said ran cool for 1 month now it's like before I fixed it? What could it be?
