Where is the water temperature sensor located on the Wuling Hongguang?

The water temperature sensor on the Wuling Hongguang is located at the engine's outlet pipe. The Wuling Hongguang uses a water-cooled engine, which relies on coolant continuously circulating within the engine for heat dissipation. Taking the 2021 Wuling Hongguang as an example, it belongs to the microvan category, with body dimensions of: length 4390mm, width 1660mm, height 1750mm, a wheelbase of 2720mm, a fuel tank capacity of 50 liters, and a curb weight of 1185kg. The 2021 Wuling Hongguang features a MacPherson strut front suspension and a leaf spring rear suspension. It is equipped with a 1.2L naturally aspirated engine, delivering a maximum horsepower of 76PS, a maximum power of 56kW, and a maximum torque of 110Nm, paired with a 5-speed manual transmission.
I'm a car mechanic and often encounter issues with the Wuling Hongguang's coolant temperature sensor. It's usually located on top of the engine block, near the water pump or thermostat housing, on a coolant pipe fitting. You can spot it easily when you pop the hood—it's a small electrical connector with wires. This part is super important as it monitors coolant temperature and sends data to the car's computer. If it fails, the temperature gauge might go haywire, the cooling fan could spin out of control, and the engine may overheat, leading to skyrocketing fuel consumption or even a blown head gasket. I've replaced countless of these: just wait for the engine to cool, drain some antifreeze, and unscrew it with a wrench. Never attempt this on a hot engine—scalding or fluid spray could cause serious trouble. During routine maintenance checks, take a quick glance to ensure the connector is clean and rust-free. Address any issues early to avoid unnecessary trips to the repair shop.
I've been driving the Wuling Hongguang for several years, and the coolant temperature sensor failed once in my car. Its location is quite easy to find: on the left side of the engine block, inserted into the coolant pipeline. At that time, the temperature gauge kept showing abnormalities, and the fan kept buzzing loudly until I identified the issue. Its function is to detect the temperature and transmit it to the computer. If it malfunctions, the dashboard will go crazy, and you might even experience difficulty starting the engine when cold. I recommend that owners check dashboard warnings immediately when abnormalities occur and not ignore them. Actually, locating it isn't hard—just familiarize yourself with the engine layout under the hood. The sensor is usually near the coolant pipes. Replacing it is simple, but make sure to do it when the engine is cold to avoid danger. Paying attention to coolant temperature changes while driving can help prevent major repairs, ensuring safety and peace of mind.
As a car enthusiast, I know quite a bit about engine details. The coolant temperature sensor on the Wuling Hongguang is generally located at the upper part of the engine block, right next to the water pipe interface. Its function is to monitor the coolant temperature so the ECU can adjust ignition timing and fan operation. If it fails, the temperature gauge becomes inaccurate, the fan may run erratically wasting electricity, and it could lead to poor combustion efficiency. The exact position varies slightly by model but is mostly in the central area of the engine. Regular checks can prevent minor issues from becoming major problems.
