Where is the water filler port for the Toyota Corolla's radiator?

[DeFrancisco]

The radiator filler port for the Corolla is located on the left side of the engine compartment near the passenger seat. The car radiator generally refers to the automobile heat exchanger, which is part of the vehicle's cooling system. The radiator in the engine's water cooling system consists of three main components: the inlet chamber, outlet chamber, main plate, and radiator core. The steps for adding water to the car radiator are as follows: 1. Turn the pressure cap counterclockwise; if you hear a hissing sound, wait until the sound stops before opening it; 2. Fill the coolant expansion tank with an appropriate amount of coolant, ensuring the level is between the MAX and MIN marks; 3. With the coolant expansion tank cap open, start the engine; 4. After starting the engine, the coolant level in the tank will gradually decrease. At this point, add more coolant to the expansion tank until the level reaches between the MAX and MIN marks again; 5. Reinstall the cap, making sure it is hand-tightened and fully seated.
