Thermostat How It Works Symptoms Problems Testing Thermostat: how it works, symptoms, problems, testing. the thermostat is the key component of the engine cooling system. the cooling system keeps the engine from overheating. the system is filled with liquid coolant (antifreeze) and is connected into a loop with a radiator, see the diagram. cooling system diagram. Here is a more detailed list of the most common signs of a bad or failing thermostat to look for: 1. overheating engine. when the car thermostat remains stuck closed, the hot coolant cannot flow to the radiator. because the hot fluid cannot be cooled down, it keeps the temperature of the engine up higher than normal.

Thermostat How It Works Symptoms Problems Testing How the thermostat works in your car. the car’s thermostat is an ingenious component that plays a key role in regulating the engine’s temperature. almost acting as a gatekeeper, it determines the flow of coolant through the engine and the radiator. in a cold engine, the thermostat remains closed, allowing the engine to warm up quickly.
