Water Level Sensor WG9925550967 Sinotruk

Product Introduction

This Water Level Sensor WG9925550967 is an OEM fluid level monitoring component exclusively for Sinotruk heavy-duty trucks (e.g., HOWO series), primarily installed in the vehicle’s coolant expansion tank or windshield washer fluid tank. It features a high-temperature resistant PBT sensor probe, a durable oil/abrasion-resistant PVC wiring harness, and a sealed automotive-grade electrical connector. Engineered to Sinotruk’s strict quality standards, it provides accurate real-time water level detection in the harsh under-hood environment of heavy-duty vehicles, resisting extreme temperatures, vibration, and chemical corrosion from coolant additives.

Core Functions

1. Real-Time Level Monitoring: Precisely detects the liquid level in the vehicle’s fluid tank (coolant/washer fluid) and converts the mechanical position change into a stable electrical signal for transmission to the instrument cluster.

2. Low Level Alarm Trigger: Automatically activates the dashboard warning light or audible alert when the fluid level drops below the safe threshold, preventing engine overheating (coolant) or loss of windshield cleaning function.

3. Harsh Environment Resistance: The sensor probe is resistant to high temperatures (up to 125°C) and chemical corrosion; the reinforced wiring harness withstands long-term vibration and friction, ensuring no signal interruption.

4. IP67 Waterproof Sealing: The fully sealed connector and probe structure prevent water, coolant, and dust from entering the internal circuit, avoiding short circuits and sensor failure in rainy or off-road conditions.

5. OEM Direct Replacement: Matches the original tank’s mounting interface, wiring pinout, and resistance signal curve perfectly, supporting plug-and-play installation without calibration or modification.
