Where is the thermostat located on the Besturn B30?

The thermostat of the Besturn B30 is located at the water inlet of the engine water pump. Introduction to the thermostat: It automatically adjusts the amount of water entering the radiator based on the temperature of the coolant, changing the circulation range of the water to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within an appropriate temperature range. The thermostat must maintain good technical condition; otherwise, it will severely affect the normal operation of the engine. For example, if the main valve of the thermostat opens too late, it will cause the engine to overheat; if the main valve opens too early, it will prolong the engine's warm-up time, resulting in the engine temperature being too low. Function of the thermostat: The role of the thermostat is to prevent the engine from becoming too cold. For instance, after the engine is operating normally, when driving at high speeds in winter, without a thermostat, the engine temperature might become too low. In this case, the engine needs to temporarily stop the water circulation to ensure the engine temperature does not drop excessively.
As someone who frequently works on cars, I can tell you that the thermostat of the Besturn B30 is usually located at the front or side of the engine, specifically where the upper radiator hose connects to the water pump. If you open the hood, you can see the upper radiator hose, and following it towards the engine, you'll find a metal or plastic housing fixed there—that's the thermostat. Its function is to regulate the flow of coolant, closing during cold starts to allow the engine to warm up quickly and opening to cool once the optimal temperature is reached. When replacing it, you'll need to drain the coolant first and disconnect the hoses. The location can be somewhat hidden, so be careful not to damage the sealing ring. Common issues include sticking, which can cause the engine to overheat or warm up too slowly. It's advisable to refer to the vehicle's repair manual for precise positioning. Remember to wear gloves to protect yourself from burns during the operation, as incorrect installation can affect performance.
I previously replaced the thermostat myself on my Besturn B30. It's located at the water pipe connection near the engine water pump, specifically on the cabin side under the hood. At that time, my car was taking too long to warm up. After locating it, I had to remove some plastic covers and pipes, which was quite time-consuming. The thermostat is usually secured with bolts at its mounting points - the position isn't overly complicated but requires patience. It functions like a temperature valve, controlling coolant circulation. After replacement, it solved my cold start issues. I'd remind everyone to first completely drain the coolant to avoid leaks before starting work. Sharing experiences can help beginners avoid detours - confirming the location is crucial.
