Then coolant doesn't flow through the engine block, and your motor is allowed to build up heat. If your thermostat works properly, it'll open up when the specified temperature is set, and coolant will flow in. If it's not working properly, then the heat will continue to build until you either shut off your motor or you blow a head gasket.
When the car is cold the thermostat is closed. When the thermostat is closed the coolant does not circulate or get in to the engine block.
It will probably overheat. answer= thermostat will not open and will prevent the flow of coolant . which will in turn do damage to your engine
The thermostat is a device which blocks the flow of coolant through the radiator until the coolant inside the engine reaches a certain temperature, at which point the thermostat gradually opens to allow enough coolant though to maintain the engine at its optimum operating temperature. The thermostat then controls the flow of coolant to keep the engine at that temperature irrespective of engine load and operating conditions. Without a thermostat and engine warms up more slowly and will never reach its optimum temperature. This causes increased fuel consumption and increased wear on the moving parts.

The coolant could have frozen in the radiator. If that happens the coolant in the engine will just get hotter. It could also be the thermostat.
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.
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.

The temperature of the coolant entering the heater core is controlled by the engine thermostat. The engine coolant thermostat is generally located at the engine end of the upper radiator hose.
A thermostat blocks water flow until the engine reaches operating temperature. Without a thermostat installed the engine will be very slow to warm up in cold weather and interior heat will be delayed.
If the thermostat does not open, it will prevent the coolant from circulating through the engine properly. This can result in the engine overheating and potentially causing damage. It is important to replace a faulty thermostat to prevent engine issues.
When you start the engine, the thermostat is closed. After the coolant warms up the thermostat begins to open up allowing coolant to flow thru the raditor. When first started the temp will go a little past what the thermostat is set to open at. After the water begins to flow thru the radiator, the temp will fall to whatever the thermostat is set at. The thermostat holds the coolant in the engine until it warms up. As soon as the engine is warm, the thermostat opens allowing cold coolant outside the engine to mix with warm coolant. The temp drops, the thermostat closes again, until all the coolant is warm.
