Water Temperature Sensor for Great Wall M2 (4G13/4G15) – 3611070-EG01

The water temperature sensor 3611070-EG01 is an engine coolant temperature (ECT) sensor primarily used in Great Wall and BYD vehicles.

Description

Key Specifications
Part Number: 3611070-EG01 (OEM) / F01R064905 (Bosch)
Manufacturer: Typically supplied or manufactured by Bosch
Sensor Type: NTC (Negative Temperature Coefficient) thermistor
Vehicle Compatibility Examples: Great Wall C30, Florid, Haval M2/M4, and BYD F0
Engine Compatibility: Commonly used with 1.3L and 1.5L VVT engines (e.g., 4G13 and 4G15)

Operating characteristics: As a standard NTC thermistor, its resistance decreases as the engine temperature rises. Standard NTC coolant sensors typically operate on a 5V reference voltage supplied by the ECU; the output signal is approximately 2V when the engine is cold, dropping to about 0.5V when the engine reaches its optimal operating temperature.
