Product Appearance Description

This water level alarm switch features an all-black plastic structure with an M18×1.5 thread design and an integrated wire harness, fitting the installation interface of Dongfeng Kinland models.

1.The main body is a black plastic hexagonal structure with a threaded protective cap on the top and a standard M18×1.5 external thread on the bottom, which can be directly screwed into the coolant expansion tank installation position.

2.The wire harness is an integrated design with a protective outer layer, which is anti-aging and wear-resistant, adapting to the high-temperature and humid 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 Dongfeng Kinland series models, it can directly replace the original part to solve problems such as non-functional or false liquid level alarms.
