The coolant should circulate through the entire water system.
The thermostat is typically mounted on the engine block or in the coolant passage, and it controls the flow of coolant to and from the engine. When the engine is cold, the thermostat remains closed to allow the engine to heat up quickly. Once the engine reaches the desired operating temperature, the thermostat opens, allowing coolant to flow into the engine and maintain optimal temperature. Therefore, the thermostat itself does not move up or down but operates based on temperature changes.
The thermostat in a car regulates the coolant temperature inside the engine. When the engine is cold, the thermostat is closed, allowing the heat from the combustion chamber to heat the fluid (coolant) in the coolant galleys in the engine block. Once the engine reaches an optimal temperature, the thermostat opens, allowing coolant to flow through the radiator. The thermostat then controls the flow of coolant to hold the engine at its optimum operating temperature, irrespective of engine load and operating condtions.
It is not supposed to be on when engine is running unless there is a problem.
it will allow coolant to leak ut. once the coolant gets low then the vehicle can over heat
It collects the expanding coolant that is heated by the engine and recycles it back into the coolant system once it loses enough heat. The radiator overflow tank works in conjunction with the radiator cap to protect the engine and prevent coolant loss due to overflow. Source: Quora.com
Ive never heard of draining coolant plugs except on a diesel engine . Once you drain the coolant and flush the system it should be fine
The plastic coolant reservoir on the fender feeds directly into the coolant system. Just add coolant to the reservoir and if you have drained the coolant or otherwise emptied the system, you may need to check the level in the reservoir after running the engine, or more accurately, after the engine has cooled. Once the coolant level has stabilized, just check it periodically to make certain that the coolant level never gets too low.

To bleed the coolant system on a 2000 1.8 Ecotec engine, first ensure the engine is cool, then remove the radiator cap. Start the engine and let it idle, allowing the thermostat to open. As the engine warms, check for air bubbles in the coolant reservoir; add coolant as necessary to maintain the proper level. Once the thermostat opens and the bubbles subside, replace the radiator cap securely to complete the process.
blue is when the engine is cold & when it turn off it means that the engine is at the right temp..
To bleed the coolant system on a 2003 Mach 1 Mustang with a 4.6 DOHC engine, first ensure the engine is cool and remove the radiator cap. Start the engine and let it idle with the heater set to maximum heat; this allows the coolant to circulate. As the engine warms up, check the coolant level and add coolant if necessary, continuing to do so until no air bubbles are visible. Once the engine reaches operating temperature and the thermostat opens, turn off the engine, allow it to cool, then recheck and top off the coolant level before securely replacing the radiator cap.
No, the thermostat controls the temperature of the engine coolant. As long as the coolant temperature is below the thermostat set-point, the thermostat remains closed. Once the temperature arrives at the set-point, the thermostat starts to open, sending heated coolant through the radiator. The radiator then cools the heated engine coolant and the water pump forces the coolant back through the engine. The heater control valve allows more or less of the engine coolant through the heater core. Since the coolant should be very near the set-point temperature of the thermostat, you should be getting hot water through the heater core to warm the inside of the vehicle. The engine coolant is there to keep the engine from melting down or from breaking metal parts and burnng off the oil. It just happens that the heated coolant is useful to warm the inside of the vehicle.
