Thermostat question

It's a 22" radiator. The contour fan setup is for a 26" radiator. Plus the contour fan set up is almost 3.5" thick, he's only got about 2" to the power steering pump pulley.

That pulley set up seems to be a killer. If it's the underdriven set up I think it is, it really could be the source of most of this.

That tends to make one think that if you ran your engine 10% slower then it could overheat, but it doesn't.
There is other issue's going here.
