Where is the thermostat located in the Nissan Qashqai?

The thermostat in the Nissan Qashqai is located at the connection point between the lower radiator hose and the engine block. Below is expanded information about the thermostat: 1. A thermostat is an automatic temperature-regulating device, typically containing a temperature-sensing component. 2. The thermostat functions by automatically adjusting the amount of coolant entering the radiator based on the coolant temperature, altering the coolant circulation range to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within an appropriate temperature range. Here are relevant details about automotive thermostats: 1. If the coolant temperature exceeds 110°C, stop the vehicle, turn off the engine, and open the engine hood. Touch the upper radiator hose in the coolant radiator; it should be very hot. Then touch the lower radiator hose, which should also be very hot. If there is a significant temperature difference between the upper and lower hoses, the thermostat is confirmed to be faulty. 2. If the engine takes an unusually long time to reach normal operating temperature, stop the vehicle and allow the engine to cool to ambient temperature. Restart the engine and drive until the dashboard temperature gauge reaches approximately 70°C. Then, stop the vehicle, turn off the engine, and open the engine hood. Touch both the upper and lower radiator hoses. If there is no temperature difference, the thermostat is confirmed to be faulty. 3. Use an infrared thermometer to measure the thermostat. Aim the infrared thermometer at the thermostat housing. When the engine starts, the inlet temperature will rise while the thermostat remains closed. Once the temperature gauge reaches 70°C, measure the outlet temperature, which should suddenly increase. If there is no temperature change, it indicates poor thermostat performance, and replacement is necessary.
When servicing the Nissan Qashqai, I often encounter thermostat installation issues. It is typically located in the upper section of the engine within the engine compartment, near the water pump connection, specifically at the hose interface. You can easily spot it upon opening the hood, as its design makes it highly recognizable. The thermostat regulates coolant flow; if the engine frequently overheats or exhibits unstable water temperature, it's likely malfunctioning. After locating it, I advise against DIY removal due to the need to drain coolant and the risk of burns—professional shop handling is recommended. Regular inspection of the engine cooling system can prevent failures, avoiding roadside breakdowns or engine damage. Safety first: always check the temperature gauge for abnormal signals before driving.
