The tutorial for replacing coolant in the Qashqai: 1. Drain the old coolant, then flush the fluid channels with clean water, allowing the water to continuously flow through the engine cooling system. After that, start the engine and let it idle for 3 to 5 minutes to circulate the water; 2. After about an hour of draining, add the new coolant through the radiator hose of the water tank. Then, add another bottle of coolant to the coolant reservoir until it is nearly full; 3. Start the engine and let it run for about 10 minutes. At this point, the coolant level will drop slightly as some air is expelled from the cooling system. Add more coolant until it reaches the MAXT mark on the reservoir. The Qashqai's body dimensions are 4315mm in length, 1783mm in width, and 1606mm in height, with a wheelbase of 2630mm.

Changing the coolant in a Qashqai is pretty straightforward, I've done it myself a few times. First, make sure the car is completely cooled down—wait at least half an hour after the engine has cooled to avoid burns. Park on a clean surface and pop the hood. There's a drain plug at the bottom of the radiator; use a wrench to loosen it and place a large pan underneath to catch the old fluid. Don't forget to wear gloves, as the old coolant is corrosive. Then, reinstall the drain plug and flush the system with distilled water a couple of times to rinse out any debris. Next, add new coolant—follow the type recommended in the Qashqai manual. I usually use ethylene glycol-based coolant, filling the expansion tank up to the MAX line. Start the engine, turn the heater to the hottest setting, and let the system bleed air for a few minutes while checking if the fluid level stabilizes. Finally, clean up your tools and inspect for any leaks. The whole process takes about 40 minutes—don't rush it. Coolant protects the engine from rust, and regular changes can save you from costly repairs. Always use OEM or compatible coolant; mixing different brands can cause issues.

As a seasoned car owner, my top priority when changing coolant is safety. The radiator system of the Qashqai gets extremely hot and can burn skin on contact, so it must be done after the car is parked and cooled down. My toolkit is simple: a bucket of new coolant (the color and specifications recommended by Nissan), gloves, a drip tray, and a wrench. During the operation, first locate the bottom drain point and slowly loosen it to drain the old coolant. Safety tip: Don't do it in the garage—old coolant is toxic and must be disposed of properly; never pour it down the drain. Before adding new coolant, it's best to flush the system with clean water, but don't overdo it. When refilling, pour slowly to avoid airlocks, then start the car to bleed the air. After checking that the fluid level is stable, tighten the cap securely. Every time I finish, I monitor the temperature gauge for a few days to ensure everything is normal. The whole process is straightforward, but having a helper is even better. Changing the coolant protects the engine for winter, and it's typically done every two years on average.

Regarding the replacement of coolant for the Qashqai, I recommend sticking to the maintenance schedule without delay. Coolant isn't just for preventing freezing; it also protects against corrosion and overheating. Typically, it should be replaced every two years or every 30,000 kilometers, depending on driving conditions. I always use the coolant specified in the Qashqai's manual, and avoid mixing different colors. The steps are few but precise: with a cold engine, open the cap to drain the old fluid, clean thoroughly, flush with some water, add new coolant, bleed the system, and then check the fluid level. Simple tools are sufficient, making it a time and effort-saving task. Timely replacement extends the engine's lifespan.
