Product Introduction 1105130LE6C0 Water Level Sensor is an important monitoring component for HFCN721 light truck cooling system. It detects the liquid level of coolant inside the expansion tank and transmits real-time signal to vehicle ECU and dashboard. This aftermarket replacement sensor resolves false low-water alarms, no signal output and reading failure caused by internal circuit damage or aging probes of original sensors. It helps drivers monitor coolant condition timely and avoid engine overheating risk due to insufficient coolant for light commercial vehicles.
Product Advantages Adopts corrosion-resistant sensing probe that can withstand long-term contact with antifreeze coolant. Sealed plastic housing prevents liquid penetration and short circuit. Stable signal output ensures accurate level feedback under vehicle vibration. Each unit passes signal calibration testing before delivery, easy to install and matches original connector for reliable long-term monitoring.
