How to Replace Antifreeze in Qashqai?
2 Answers
Method for replacing antifreeze in Qashqai: 1. Unscrew the radiator cap, open the radiator drain valve, usually located at the bottom of the car, to drain the old antifreeze. 2. Clean the cooling system. 3. Stop adding clean water, wait for the water to drain completely, and then close the drain valve. 4. Add new antifreeze until the liquid level is between the max and min marks. Additional information: The Nissan Qashqai's antifreeze should be replaced every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding. Long-life antifreeze can last up to three years. If suspended matter, sediment, or discoloration is found in the antifreeze, replace it promptly and clean the system.
Last time when my Qashqai needed an antifreeze change, here's how I did it following my usual car maintenance routine: First, park the car on level ground and make sure the engine is cold. Then, unscrew the plastic drain valve at the bottom left corner of the radiator using a 10mm socket – don’t forget to place a basin underneath to catch the old fluid. After draining, flush the radiator with a hose until clear water runs out. Pay special attention to cleaning the reservoir tank thoroughly, as it tends to accumulate sediment. When refilling, use Nissan’s genuine blue antifreeze and pour it up to the MAX line on the reservoir. Here’s the crucial part! Start the engine and wait for the cooling fan to cycle twice. Once the engine warms up, manually squeeze the upper radiator hose several times to purge air – the Qashqai doesn’t have a dedicated air bleed screw, so this step is essential to prevent water pump noise. After driving for a couple of days, recheck the fluid level as top-up is usually needed. Always keep an old towel handy to wipe any spills during the process.
