Test the thermostat in your car to see if it is operating normally : Multi-thousand tips to make your life easier.

A thermostat is a device used to regulate a system’s temperature and keep it at a certain level. In car engines, a thermostat keeps coolant in the engine until it reaches a certain temperature. Once that maximum temperature is reached, the thermostat opens and lets water flow through to the radiator for cooling. A broken thermostat can cause overheating or inadequate heating of your car’s engine. If you think the thermostat is causing your car to overheat, it is best to have it removed or replaced. Learn how to test the thermostat in your car to see if it is operating normally and, if not, determine the source of the problem.

• Remove the thermostat from your car. Open the hood and look for the hoses between the radiator and the engine. The thermostat is typically inside a hose between the engine and the radiator. Unbolt it and remove it completely from the vehicle using a socket wrench set. Check if the thermostat’s rated temperature is indicated; this is usually near the boiling point of water.
• Heat the thermostat in a pot of water. Prepare a pot of water and place the thermostat in it. Most thermostat models are designed to function just below boiling point, because this is usually the temperature at which an engine overheats. Slowly begin to heat the water. Keep an eye on the thermostat as the water heats.
• Watch the thermostat. Before the water starts to boil, watch whether the thermostat opens. If the thermostat’s hole opens, it is operating properly. A failed or broken thermostat will not open. You will know it is working when it opens to let water flow through to the engine and radiator.
• Use a flashlight when needed. If there is not enough light, use a flashlight to check the thermostat. You will notice that the opening becomes larger as the temperature rises.
• Replace the thermostat if needed. If you suspect a failed thermostat is causing your car’s engine to overheat, you can have it replaced. It may be best to replace it with a new one, although your car will still run properly even without a thermostat installed.
• Let the thermostat cool if it is operating. If the thermostat opened during your test, there is no need to replace it. Let it sit in the pot for a while to cool gently before reinstalling it in the engine.

Your car will run normally without a thermostat, so you can easily run to the auto parts store or garage to buy a new one. However, during winter months, your engine might take a long time to reach proper operating temperature. Also, your car’s heater will not work properly, as the engine cannot provide enough heat to warm the interior.
