What person in any capacity would think it is good to allow an aluminum engine to increase 30 degrees, then decrease 32 degrees, in a period of less than 10 minutes.
On my recent trip to the mountains, as long as I was moving well, my temp was always right at 194 up steep hills and down.
Twice I got stopped for road construction at the top of a very long and steep hill. Within less that 5 minutes the engine temp went from 194 to just touching 224 before we started moving. Oil temp went to 212, and trans went to 206.
I was at the very top both times, so as soon as we started moving it was all downhill. Temperatures were quickly dropping, with engine getting down to 190. Transmission and oil temps went down just as quickly.
I don't care who, what, or why. This is not good for an engine. Too much expansion and contraction in a very short amount of time, plus just the extreme heat in the fluids and parts.
It's ridiculous this can't be adjusted in the ECM. I guess I will just have to put in a pusher fan with a toggle switch to keep temperatures under control. I was going to last summer when I first bought the truck, but put it off.
If anyone knows a way to adjust these settings, pleas post it here.
