What are the effects of removing the thermostat?

[ReedLynn]

If the thermostat is damaged, it may cause the coolant to continuously circulate in the large loop or the small loop. Below is relevant information about the thermostat: 1. The thermostat controls the circulation path of the coolant. Most vehicles use water-cooled engines, which rely on the continuous circulation of coolant within the engine to dissipate heat. 2. In water-cooled engines, the coolant has two circulation paths within the engine: the large loop and the small loop. When the engine is first started, the coolant circulates in the small loop, bypassing the radiator, which helps the engine warm up quickly. 3. Once the engine reaches its normal operating temperature, the coolant switches to the large loop, maintaining the engine within the optimal temperature range. The thermostat is responsible for switching between the large and small loops based on the coolant temperature.
