Fan clutch ?
Been having a problem with my '99 7.4 (big block) running too cold, usually well below 180. This seems to cause the 'burb to get worse mpg than it should. It was suggested I swap out the t'stat to a 195, so I just did, no change. In talking to a mechanic (pro) I know we noticed the air behind the fan was cold, really cold. Then we noticed the fan was turning when it should not be.
Anyone have similar experience? I want a bit more input before I spend the $$ on the fan clutch.
