i bought a car that was resontly rebuild and they used oversizd piston rings theres about 400 miles on the engine and i was wonder my car over heats like if i go easy on it it wont over heat but if i go fast like not over 50 it will start to over heat...what can be the cause??

im pretty sure im getting curculation the hose at the bottom heats up wayyyyy slower then tha hose ont he tiop of the radiator and yes my radiator fan comes on as soon as i turn my key to the ready to start position idk what its call but a click before u start it..im not sure if the water pump was replaced or not i know its a D15B7 with a Y8 head
very high compression from what ive been hearing i need sugestions and help it over heats runs fine but i just cant find why its ****ing over heating
