360 running hot…very hot

IS that a three or four row radiator? Sometimes, you run into the phenomena where you have too many rows and it actually blocks air flow. That's why most all competent radiator companies and cooling "experts" recommend a two row radiator with extra large tubes, usually 1" - 1.5" wide. If you can shoot the radiator in the places I recommended and let us know temps going in and coming out of the radiator, and around the thermostat housing, that will give us a good idea of how well the radiator is shedding heat. Also I cannot tell with the fan spinning how far it is into the shroud.
