ok.. i'll have the radiator fan replaced over the weekend..hopefully yun na nga yung solution...

pero ano kaya yung reason kung bakit nagooverflow yung water sa reservoir bottle at the time na tumataas yung temp, tapos halos wala nang water sa radiator? as in na top up yung reservoir bottle with the water+coolant mixture. yung radiator fan na rin ba culprit nun, or something else?
