The engine coolant thermostat is a valve that controls the flow of coolant through the engine. It is located in the engine compartment and is typically located near the front of the engine, near the radiator.
The thermostat is designed to open and close based on the temperature of the coolant. When the engine is cold, the thermostat is closed, preventing coolant from flowing through the engine. As the engine warms up, the thermostat begins to open, allowing coolant to flow through the engine and help regulate its temperature.
A faulty thermostat can cause problems with the engine’s cooling system. If the thermostat becomes stuck in the closed position, it can cause the engine to overheat. If the thermostat becomes stuck in the open position, it can cause the engine to run too cold, which can also lead to problems. If you suspect that your engine coolant thermostat is not functioning properly, it is recommended to have it checked by a mechanic.
