Hi,
I got tired of the temp going to 210 or 220 so I put in a new 180 T stat and built a fan shroud for the aluminum rad, mounted the same 16" puller fan on the shroud,now about 2 1/2" back from the rad. WHAT A DIFFERENCE ! Runs at 185* all day long no matter how hot it gets.
The shroud is the cool ticket.
