How much water should be added to the Corolla radiator?

The Corolla radiator requires 4 liters of water per refill. Antifreeze is a coolant with special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent properties such as freeze protection in winter, year-round scale prevention, and corrosion resistance. The exact amount of water to be added depends on the actual situation. If the water level in the radiator is below the corresponding water level mark, it is necessary to add water up to the MAX mark on the reservoir. The Corolla has body dimensions of 4630mm in length, 1775mm in width, and 1480mm in height, with a wheelbase of 2700mm. This model is equipped with a newly developed inline four-cylinder 1.8L engine featuring dual VVTi technology. Paired with either a 6-speed manual transmission or a 4-speed automatic transmission, it delivers a maximum power output of 100kw and a peak torque of 175nm.
I usually check the coolant myself when driving my Corolla. The so-called 'water tank' actually refers to the expansion tank - that white plastic container marked 'Coolant' in the engine bay. Never directly unscrew the radiator cap on the engine, it's extremely dangerous! When topping up, make sure the engine is cold, and just maintain the fluid level between the Min and Max marks on the side of the tank. Adding about 500ml is usually enough to fill it up. Remember never to use tap water or mineral water as they can cause rust and scale buildup - always use dedicated antifreeze coolant. Also, never mix different colored coolants. I learned the importance of monthly expansion tank checks last year when I had a coolant leak - it's also a good opportunity to inspect hoses for cracks.
