From a cold start, your vehicle’s thermostat will stay closed and you won’t notice any coolant flowing into your radiator. Leave the vehicle running for about 10-20 minutes so it can reach its optimal running temperature.
What happens when the thermostat goes out in a car?
A bad thermostat can cause the car to swelter, as the thermostat is a heat-sensitive control device situated at the radiator hose. If the thermostat is stuck closed, the antifreeze won't flow from the radiator, resulting in the car overheating. Thus, if this happens, one of the possible causes is a broken thermostat.
Can a bad thermostat cause power loss?
If your thermostat is not functioning correctly, the motor will take longer to heat. However, it does not cause loss of power. In fact, it may actually increase power as the motor operates at a colder temperature with a bad thermostat.

Can a car turn on without coolant?
The answer: nothing good. Coolant circulates through your car and extracts heat from various components, keeping their operating temperature within normal parameters. Without coolant, there's nothing to extract this heat, and these parts quickly overheat and break down.
Why is my car overheats but the temperature gauge normal?
If the temperature gauge consistently shows the engine is warmer than normal, have your cooling system checked ASAP. There are many possible reasons that your engine is running hot, including low coolant levels, a clogged or closed thermostat, a failed head gasket or a water pump malfunction.
