Something I noticed however, is once I replaced the radiator, the average operating temp is around 197, and it doesn't take much for the truck to go up to 205. I left it idling in open air, and it went up to 216. At that point I started driving and it cooled off, went back to 197ish.

So about 3 or 4 weeks ago my radiator burst right under the upper radiator hose, dropped a lot of coolant, but thankfully made it home. My scangauge read it got up to 225, where I pulled over, and let it cool down a little and continued on home. Im worried it caused damage, but I replaced the radiator, topped off the coolant and seems to be running fine.

Prior to the burst, the truck was very constant in its cooling. It would always be around 182 to 187. I was happy with it, and even when idling for long periods of time, the truck would never go over 200, always 197 max.

Is this normal operating temps? Should I be worried? I live in AZ and I want to be prepped for the summer heat, and if the truck is going as high as 216 on winter nights, im not too sure what to think of it.
