Where is the Thermostat Located in a Car?

Automobile thermostats are generally installed at the upper water outlet of the engine. The thermostat must maintain good technical condition; otherwise, it can severely affect the normal operation of the engine. If the main valve of the thermostat opens too late, it can cause the engine to overheat. Conversely, if the main valve opens too early, the engine's warm-up time will be too short, resulting in the engine temperature being too low. Below is relevant information about the thermostat: 1. The thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature to ensure the engine operates within an appropriate temperature range, which helps save energy consumption. This is because the engine consumes more fuel at low temperatures and can suffer greater damage, including the risk of carbon buildup and a series of related issues. 2. Under normal circumstances, when the engine starts cold, the operating temperature is very low. To allow the temperature to rise more quickly, the thermostat controls the flow (with the main valve closed), directing the coolant from the pump into the water distribution pipe, bypassing the radiator. This is known as the small circulation cycle. Once the coolant temperature reaches 87 degrees, the thermostat valve opens, allowing the coolant to flow through the radiator, and the cooling system enters the large circulation cycle. 3. Generally, about five minutes after a cold start, the coolant temperature should reach the normal range of 85-105 degrees. If the engine takes an unusually long time to reach the normal operating temperature or if the temperature rapidly exceeds 110 degrees, it may indicate a malfunctioning thermostat.
