Your Nissan thermostat is responsible for regulating the temperature of your vehicle by controlling the amount of fluid that goes into the radiator. When your Nissan thermostat starts to fail, you'll probably notice a few symptoms, including overheating, incorrect and often low temperature gauge readings, your cooling fan may run too much, the heating system may malfunction, not be as warm as it should be, you may notice a high idle, your fuel mileage may suffer, and you may hear knocking or pinging when you press the fuel pedal. Replacing your Nissan thermostat is not a complex or difficult repair and can usually be completed with basic tools and a bit more than an hour of your time.
