Check you anti-freeze level in the radiator and overflow bucket. If they are low fill them both to the proper levels. Then look for a leak. If they are not low then check the thermostat. It could be stuck wide open which won't allow the cooling system to build up any heat.
Thermostat gixed mine until....it stuck open. Lol no biggie fix.
