Does the Qashqai radiator need water?

The Qashqai radiator does not require water; it needs to be filled with coolant. The functions of coolant are: 1. To provide freeze protection for the engine against low-temperature environments; 2. To prevent the cooling liquid from freezing and cracking the radiator or damaging the engine cylinder block and cylinder head when the car is parked in cold winter conditions; 3. To offer efficient heat dissipation. The Qashqai is a compact car under Dongfeng Nissan. Taking the 2021 Qashqai Intelligent Edition as an example, its body dimensions are: length 4401mm, width 1837mm, height 1593mm, with a wheelbase of 2646mm, and the body structure is a 5-door, 5-seat SUV.
The water tank in the Qashqai is actually the coolant reservoir of the cooling system, not for adding water but for checking the coolant level. When I first bought my Qashqai, I made the mistake of adding plain water, which almost caused the engine to overheat. Coolant is a special mixture that prevents freezing, boiling, and corrosion. Adding pure water dilutes it and can corrode internal engine components. Routine checks are simple: wait until the car is cool, open the hood, locate the transparent plastic coolant tank, and ensure the fluid level is between the MIN and MAX marks. If it's low, don’t rush to add water—instead, purchase OEM or compatible coolant concentrate and top it up in the correct ratio. Having a technician perform a thorough inspection during annual maintenance is even more convenient. Safety comes first to avoid breakdowns on the road. The condition of the coolant tank affects engine longevity, so developing a habit of regular checks can save a lot on repair costs.
