Running your engine at higher temperatures makes it more efficient. Ideally you would want it to have it running just below the fan trigger temp all the time, but that's just not possible.

My elantra runs at 196 and the fan kicks in at 220.

Since dash gauges are so innacurate, I would not suggest running your truck fanless without a way to accurately monitor coolant temps.

Why is this true? It seems to go against all logic. Now I can understand you guys that live up north wanting to get engines heated up quickly, but here in florida its so hot the engine is almost at temperature while parked .. LOL

Seriously though, I was think about running without a thermostat in order to bring engine temps down to a 160-180 range or lower. Someone please edumacate me ...

Maybe you are confusing performance and efficiency.

Under certain limits:
- A colder engine performs better while a hotter one is more efficient.
- A richer engine performs better while a leaner one is more efficient.
