Where is the thermostat located in a Corolla?

Corolla's thermostat is positioned at the lower water pipe, near the bottom of the generator. The car thermostat is a valve that controls the flow path of the engine coolant. It 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 in saving energy consumption. The Toyota Corolla is a compact sedan. The dimensions of the 2019 Corolla model are 4630mm in length, 1775mm in width, and 1480mm in height, with a wheelbase of 2700mm. The 2019 Corolla is equipped with a 9NR engine model, offering two displacement options: 1.2T and 1.8L, and comes with one transmission choice of continuously variable transmission (CVT). The engine delivers a maximum power of 85 kilowatts, a maximum horsepower of 116, and a maximum torque of 185 Newton-meters.
I've been using a Toyota Corolla for ten years, and the thermostat is usually installed in the engine compartment, near the water pump or upper hose connection. The exact location depends on the model, like the 1.6-liter engine version, where it's at the upper hose connection of the cylinder head—it looks like a small valve. Its main function is to control the flow of coolant. If it fails, the engine can easily overheat or have trouble starting. That time my old Corolla's temperature spiked, I spent a long time checking and found the thermostat was stuck. I even had to remove the air filter box to get a clear view of its position. My advice is not to rush when inspecting it—wait for the engine to cool down before working on it, or you might get burned. Taking a look at it during regular maintenance can save a lot on repair costs.
