Im running a brand new fan clutch and they fan is about 3/4 inch away from rad. Like i said i dont run a shroud on my roadrunner or challenger and they run 180. I think it's way beyond a shroud ,because i had an HHR elec fan with shroud and it was doing the same thing.

How can i tell if my lower rad hose is collapsing while driving ? Theres a ton of pressure in it when engines off...

Could i have a blown head gasket/ cracked head causing this overheating issue without the signs of running poorly or smelling antifreeze?
