My car keeps overheating but no leaks, and the thermostat hose still gets hot. whats the problem? its a 99 crown vic police package

Since this vehicle has a thermal clutch fan I'd start there

are ALL the hoses getting hot?

• upper rad hose
• lower rad hose
• heater hoses

A cooling system consists of a water pump, cooling fan, thermostat, radiator hose, hose clamps, radiator, radiator cap and coolant. Engine coolant is used to transfer heat from the engine to the radiator by the cooling system. The radiator removes heat from the coolant by forcing air through the radiator cooling fins. Without coolant your engine will overheat and if left unattended severe engine damage will occur. Coolant leaks are a common problem to an overheating engine. So once again, make SURE that you are not leaking coolant. If you have to, monitor it with a towel or cloth of some sort. My knowledge here isn't too well, but if you are losing pressure, that could be a problem as well. So maybe put a pressure gage on it, and monitor how much pressure you are gaing or losing. So triple check that you are not leaking coolant. Also keep in mind that the leak could be internal. Causing even more problems that should be fixed ASAP

First i would start with the little things. First check to make sure the heat sensor isn't bad. Your car could be just telling you that it is over heating, but it could be a miscommunication betweent the computer and the sensor. Also check you antifreeze/coolant level, and make sure it is good. It may need to be flushed. Other than that, witht the info you provided, you car should be in good working condition.
