Start with the basics. Turn the heater controls to hot. Remove the radiator cap and drain the coolant. Flush the system out with water. Replace the thermostat, and pour in a 50/50 mix of the proper Anti-Freeze and Distilled water. Replace any hoses that need replacing while doing this. Start the engine with the cap off and bleed all air from the system. Use bleeder valves if equipped. Keep the radiator full at all times. You should see water flowing once the thermostat opens. If not suspect a bad water pump. Once this is done, replace the radiator cap and turn on A/C. One fan should run. Shut off A/C and let engine run until it reaches operating temp. Watch the temperature gage and once it gets above mid point the fan should come on. If not check the fuse.
If there is no cooling system, the engin will overheat.
The cooling system helps keep the car from running too hot. A diagram for the 1998 Ford Taurus cooling system can be found in the car's maintenance or repair manual.
Yes, engine oil and automatic transmission oil can both get into the cooling system.
A cooling system schematic for this car can be found in the maintenance manual. It can also be found in the repair manual of the car.
It Will usually have an air pocket in the cooling system. But it may just be the Air Conditioning equalising after you shut the car off. Start by filling the cooling system
Poor coolant circulation in the cooling system.
drain the whole cooling system and refill it. You will never know if you don't give details of your car!
The cooling system is a closed system. If there is smoke (probably steam) there must be a leak in the cooling system somewhere.
Possibly over heating and worst case scenario a blown engine.
