Answer for What faults can develop in a thermostat valve ?

If the thermostat valve does not open even at a temperature of TOOTGOL 181 Automobile Engineering 60° to 70°C, the temperature of the engine goes up very high and this badly effects the working of the engine. We can come to know about the temperature of the engine through the temperature gauge. Besides this, a hole develops in this valve and water starts leaking in the form of bubbles. Because of this leakage delay takes place in making adequate temperature for the engine.
