Volkswagen Jetta King Coolant Temperature Sensor 1J0959481A Three-pin Triangular Thermistor Type

For VW Jetta/Beetle (Palace) and older platforms (such as Bora, Golf 4) models, you can opt for OEM number 1J0959481A triple-terminal thermistor-type water temperature sensor. It directly replaces the original part with universal compatibility. Core function is real-time monitoring of coolant temperature, feeding signal to ECU to adjust injection and fan on/off to keep engine within optimal temperature range, solving cold-start difficulty, rough idle, high fuel consumption, and fluctuating or non-working coolant gauge or fans in summer.
