if its overheating, then the cooling components are NOT all good.

check the thermostat, radiator, and cooling fans. check electrical connections, proper operation and if all else fails, go to a mechanic for a diagnosis.

good luck!
 
if it's the original radiator, there is a good chance it is clogged

Radiator is the most important item,along with the correct amount of coolant.
You need to remember that you should add coolant first,then top off with water.
I always error on the coolant side running more than 50%.
