Hi there, Check for any external coolant leaks, check the pressure cap is working, replace the thermostat, clean and flow test radiator, check that engine cooling fans are working. These are the most common causes of overheating, next to a head problem.

i would suggest to first check your thermostat if stock closed to test your thermostat have container and thermometer to check at what point that your thrmostat opens if it open to late or not at all change your thrsmostat but if normally opens at 70deg then thts normal .
check your thermostatic fan which is attached to fan blade rotate manually the thermostatic fan if there is a snug or some resistance while turning thats good but if no resistance at all then its time to change your thermostatic fan
then send your radiator assy to qualified repair station to overhaul your radiator might be most of the cooling fin internally are clogged
check belts tension
check radiator cap
check hose leaks
check water pump leaks or worn out bearing
hope this help you
