Hello there,

It could be a number of things:
Beside what you’ve already replaced, it could be:
*coolant leak (internal or external)
*clogged cooling system (back flush your system.)
*bad radiator cap (pressure test it, replace if bad)
*loose serpentine belt (bad belt or bad tensioner, maybe both)
*problem with cooling fans (do they come on when your car starts overheating?)
*collapsed lower hose
*bad coolant sensor (it should be located right by the thermostat housing)
*too much exhaust backpressure
