I went to the effort of installing fan shrouds on two cars; feeling proud.
Temp gauge appeared to stay the same.
Soon after, car 1 fought back and I needed to work on H2O pump.
Was a pain installing factory correct shroud, so up in the attic it went.
Later I did maintenance on car 2 and I left that shroud off as well.
Back to square 1.
I have a lame theory that no shroud helps reduce underhood temps; that's my theory and I'm sticking too it unless global warming wins the battle
