Where is the drain valve on a Corolla?

[MacLane]

Toyota Corolla's radiator is located at the front of the engine, right behind the front grille where it faces the wind. If you need to replace the coolant, the radiator's drain valve is positioned at the lower right side of the radiator's back (not at the very bottom) as a white plastic plug. Removing this plug will allow the radiator fluid to drain out. Precautions for removal: Never remove the radiator cap when the engine is hot. High-pressure engine coolant may spray out from the radiator, potentially causing severe burns. Adding coolant: After draining the radiator fluid, reinstall the drain valve properly. Then pour new coolant into the coolant filler port located in the engine compartment.
