The location of the water temperature sensor on the Buick Excelle: It is situated at the engine's outlet pipe. The water temperature sensor is a device that provides the car with water temperature signals. Taking the Excelle 2020 15N Manual Elite as an example, the car has dimensions of 4468mm in length, 1765mm in width, and 1469mm in height, with a wheelbase of 2611mm. It is equipped with a 1.3L naturally aspirated engine, delivering a maximum power of 79kw and a maximum torque of 133nm. The front suspension type is MacPherson independent suspension, while the rear suspension type is a compound torsion beam non-independent suspension. The body structure is of a unibody type, with front-wheel drive as the driving method and electric power steering as the assistance type.
I've been driving a Buick Excelle for over ten years. The coolant temperature sensor is located in the engine compartment, right above the engine water passage near the radiator outlet. It's usually a small probe fixed near the copper pipe, visible when you open the hood. I have experience replacing this part - first disconnect the battery to avoid short circuits, then use a wrench to remove the sensor connector and clean carbon deposits. It tends to accumulate dust causing inaccurate readings. If the dashboard shows abnormal coolant temperature, you should check it to prevent engine overheating damage. I just replaced mine last time for less than 100 yuan. If you're handy, you can DIY but it's best to prepare new sealing rings and have coolant ready in case of leaks, to avoid damaging the water passage lines.
I'm passionate about DIY car repairs. The coolant temperature sensor for the Buick Excelle is generally installed at the end of the engine's water passage, near the radiator connection. Specifically, it's on an aluminum component with a small socket. During actual operation, I first turn off the engine and let it cool for half an hour, then use a multimeter to check if the circuit is live to ensure safety before unclipping the sensor. The location isn't hidden but requires good lighting—a phone flashlight works well. If it malfunctions, the temperature gauge will spike alarmingly, so don't ignore regular cleaning of the connectors to prevent corrosion. This part costs just a few dozen bucks, but take your time and handle it gently. Beginners are advised to wear gloves to avoid cuts.
