have you done anything to the cooling system? if not, the first thing i would check is the cooling level. If you have plenty, then maybe the water pump has went out. Maybe the thermostat is stuck shut. you might wanna try to bleed out any air that maybe in the system. ITs hard to help when not enough info is given. like, how many miles are on the car or if you or someone else has replaced anything lately.
