Water Level Alarm Switch 36AD-10020 M18×1.5 2-Pin Copper for Hualing Heavy Trucks

Product Appearance Description

This water level alarm switch consists of a copper probe, hexagonal threaded mounting seat, braided protective wire harness, and waterproof connector, featuring a durable and highly protective structure.

1.The copper probe is corrosion-resistant and has good thermal conductivity, with a white insulating protective sleeve, designed to be inserted directly into the coolant expansion tank to monitor the liquid level in real time.

2.The middle section is a standard M14×1.5 threaded mounting seat with a black sealing washer to ensure installation tightness.

3.The wire harness is protected by a corrugated tube, terminating in a waterproof 2-pin connector that fits the original vehicle interface, adapting to the complex engine compartment environment.

Product Function Description

1.Core Function: Monitors the liquid level in the coolant expansion tank in real time and triggers an alarm signal when the level drops below the safe value.

2.Signal Transmission: When the liquid level is low, the switch sends an electrical signal through the wire harness to the vehicle ECU or instrument panel, activating the warning light or buzzer to alert the driver to add coolant in time.

3.Fault Warning: Effectively prevents engine overheating and damage caused by insufficient coolant, improving vehicle operation safety.

4.Compatibility: Designed for Yutong Bus models, it can directly replace the original part to solve problems such as non-functional or false liquid level alarms.
