Wuling Hongguang/Rongguang S/Sail 1.4 Water Temperature Sensor 9023791 Coolant Temperature Probe

Wuling Hongguang (2010-2019), Wuling Rongguang S (2014-2018) and Chevrolet Sail 1.4L (2010-2015) models can directly install this coolant temperature sensor. This part monitors coolant temperature in real time and transmits signals to the ECU to adjust fuel spray and ignition timing, preventing engine overheating or cold-start difficulty. OEM number 9023791 matches OE parts exactly; convenient for quick stock checks. Replacement requires draining some coolant, unscrewing the old sensor, applying sealant, and installing the new part; also check for oxidation of the wiring connector. This sensor uses a high-temperature copper core for faster response than plastic parts, reducing maintenance rework due to temperature misreadings.
