2013 1500 slt 3.6

My 2013 ram slt 3.6l 2wd heat hand started off running up to the 3/4 line which was unusual but fan would kick it back down at first...then it tried to run hot so I killed engine....long story short I have replaced radiator,water pump, thermostat,and new intake gaskets ...it acted like it was fixed at first but now heater isn't blowing warm air and it's still trying to run hot.

Hoses? In older engines, sometimes the bottom (suction side) rad hose would partially collapse, reducing flow, increasing heat. Just a thought.
