                                                          First would be to visually inspect the vehicle. Start vehicle and check: steam coming from exhaust, open radiator cap to check for air bubbles, water pump, radiator, radiator hoses, intake gaskets. If no signs, with a pressure test kit, test the cooling system for leaks. If still cant find problem, take the vehicle to your local mechanic to be diagnosed.
