How do I test my car thermostat?
Start your car’s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
How do I know if my water pump is bad in my car?

What does it mean when your radiator smokes?
The radiator prevents overheating by cooling the fluid that flows around the engine block to dissipates the engine’s heat. When you see smoke coming from the radiator, it is an indicator that the radiator has not been able to do this job and the car is overheating as a result.
