Where is the water temperature sensor located on the Buick Excelle?

The water temperature sensor on the Buick Excelle is located behind the intake manifold, which is also behind the generator. The internal component of the car's water temperature sensor is a semiconductor thermistor. The lower the temperature, the greater the resistance, and vice versa. The electronic control unit measures the engine coolant temperature based on this change, using it as a correction signal for fuel injection and ignition timing. More details are as follows: 1. Taking the Buick Excelle 2020 15N Manual Elite as an example, its dimensions are 4468mm in length, 1765mm in width, and 1469mm in height, with a wheelbase of 2611mm. 2. In terms of power, the vehicle is equipped with a 1.3L naturally aspirated engine, delivering a maximum power of 79kW and a maximum torque of 133Nm.
Last time I helped my neighbor Old Zhang replace the temperature sensor on his Excelle, and I remember the location clearly. The thing is hidden behind the engine near the firewall, and you have to remove the intake manifold to see it. The old Excelle's 1.6L engine has the sensor installed next to the cylinder head water jacket outlet—it's a copper probe with a two-pin connector. You'll need a 22mm socket to unscrew it. When replacing it, remember to drain half the coolant first, or you'll get scalded like a drowned rat. Actually, it's like the engine's thermometer. If it fails, the dashboard temperature gauge will go haywire, and in severe cases, the fan might even start spinning like crazy.
