Quote from: wolf_walker on March 11, 2013, 01:15:01 pmI had a fellow that worked with metal professionally question weather the differing expansion rates of the aluminum head and steel blockwould contribute to tiny amounts of head/block/gasket wear over time with wide operating temp swings. How much time? Like 30 years and 400k + miles? ;)

There is no relationship between the two. The fan switch will only switch when the outflow of the rad exceeds some specification (like 92C - that sounds about right).The temp of the t-stat, so long as its less than 92C, won't change this fact in any way.
