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.

I've been driving my X-Trail for several years, and the radiator is something you really need to keep an eye on—it's definitely not as simple as just adding water. If the coolant level is low, just top it up with coolant; adding pure water is absolutely not an option—it can freeze and burst pipes in winter, and may even corrode the water pump in summer. Checking it yourself is easy: park the car and let it sit for a while, then pop the hood and check the level in the reservoir. If it's below the minimum line, head to an auto parts store and buy a bottle of pre-mixed coolant to top it up. Don't cheap out and buy just anything—only the factory-recommended formula is reliable. Keep an eye on the temperature gauge while driving; if it runs high, check the radiator. Neglecting maintenance for too long will reduce the cooling system's efficiency and increase fuel consumption, which isn't worth it. I check mine once a month and rarely have issues—it's practical and safe.

The radiator is part of the Qashqai's cooling system and does not require water to be added. Instead, the coolant level should be checked periodically. Adding water can impair the antifreeze properties and cause engine malfunctions. The simple procedure is: after the engine is turned off and cooled, check the fluid level in the reservoir to ensure it remains within the specified range. If it's low, top it up with the dedicated coolant. Do not overlook this—leaks or low levels can lead to engine overheating and hazardous driving conditions. For routine maintenance, it's advisable to consult a professional to ensure long-term usability.

As a Qashqai owner, I must clarify that the radiator is not for adding water but for checking the coolant. Adding pure water can corrode components and disrupt the balance. Daily inspection method: When the engine is cold, locate the transparent reservoir; if the level is low, purchase a coolant product to top it up. Ensure to use a brand-compatible fluid and avoid off-brand products. This small issue can have significant consequences—once the engine overheats, repairs can be costly. Make it a habit to check monthly for an easy and reliable solution.
