Well, it's not got a mass air flow sensor, the temp sensor wouldn't cause it to overheat, & if the pump gasket is leaking there would be water dripping fom near the belts. It can be difficult to properly refill the cooling system from the reservoir tank, sometimes an air pocket remains in the engine and it can cause your symptoms. Removing the upper radiator hose & also filling through it may work better. If it still overheats & the fan comes on then the easiest thing to try is the thermostat, it's located in the housing where the lower radiator hose enters the engine.
