I think there’s a distinction to be made between want and need.
The truck needs nothing, it’s running exactly as designed. At the operating temps most modern gas vehicles do, between 195 and 225, depending on what source you ask/look at/read.
Want… that’s all on you. You can want it to run 165 degrees, painted like a speedboat and turn on your windshield washers to simulate water/waves splashing about you… LOL.
Feel free to do whatever you want…your truck, your money.
Just make sure you’re able to separate the two. Sometimes that’s a bit blurry. I think in this case, though, it was a little more clear cut.
