It usually means that there is a faulty head gasket, but it can also indicate a particular kind of leak in the water pump.
If there is no cooling system, the engin will overheat.
Not long, combustion gases (hot) generally enter the cooling system and cause the engine to overheat.
It can if their is something wrong with the cooling system.
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.
If the car came with A/C, it would have had the 3-row radiator and a cooling system capacity of 14.7 Qts. If the car did not come with A/C, it would have come with the 2-row radiator and the cooling system capacity would have been 13.4 Qts.
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.
High pressure in a car's cooling system might be caused by exhaust gases from normal engine combustion entering the cooling system. The exhaust gases might be entering the coolant due to a head gasket that is leaking, or perhaps even due to a cracked engine block. Note that under normal operation, cooling systems are pressurized due to the heat expansion of the coolant. However, if a fairly new radiator and/or hose has burst, or if the coolant hoses connecting to the radiator are rigid with pressure, this is abnormally high pressure.
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.
