Dave,

I have noted the different behavoirs of the two engines and filtered accordingly. I will definatly be testing the visco fan clutch and clogged air flow in the rad. Probably not until this weekend, though.

Yes, it definately went to 120 deg indicated. It was warm and humid. The external temp was showing 90degF, but it behaved likewise (though less extreme) on the way home and the temp was in the 70s.

It was Jim Cathey that wired his fan. He seemed to have the most promising anecdote if he was crossing the Rockies at highway speed.

I'll post the outcome as soon as I have more to share. Thanks,
