Default Overheating uphill issue

Hi guys.. so I have a Wrx 03
No big mods..

Sti intercooler
Sti injectors
Vf48 turbo
Walbro 255 FuelPump
Uppipe STI

Stage one tune

Previous owner had the car running with straight distilled water (maybe with water wetter.. not sure)

I decided to change it from water to coolant.. some days after, car started to overheat when going uphill

I thought it was the thermostat and waterpump
Yesterday I Did the timing belt kit replacement with new oem waterpump and oem thermostat as well

Went for a drive and still overheating uphill..

I replaced rad caps, waterpump and thermostat..

Im between the radiator or the HG
Not sure what to think…. Car is not leaking , hoses are fine and oil dipstick looks clean.. no white smoke, no stalling, no rough idle..

Any ideas???
