I'm trying to figure out if it is the cooling system itself (does not cool the engine enough) or Engine (generating too much heat)...

If it is the cooling I have only 1 thing left that is not replaced - Water Pump. Is it possible that water pump is working but just not pushing coolant fast enough?

P.S. All the fans are working and kicking in properly

Cooling system parts replaced:
-Fan Clutch
-AC Thermostat
-Front Fans
-Radiator
-Radiator Top Hose
-Engine Thermostat (replace twice)
