Designed specifically to detect water in the fuel supply, this sensor sends an electrical signal to the engine control module (ECM) or illuminates the dashboard lamp, ensuring you are promptly alerted to potential issues.

Crafted to meet rigorous standards, GM Genuine Parts, including this WIF sensor, are backed by General Motors and hold the same quality as the components installed during vehicle production. Some parts may previously have been branded as ACDelco GM Original Equipment, highlighting their authenticity and reliability. GM engineers continuously update production and service designs, incorporating new materials and technologies to enhance longevity and performance.

In terms of features, this sensor boasts a black oval connector with a two-terminal blade pin design, ensuring easy integration into your vehicle's system. The limited lifetime warranty provided extends additional peace of mind, especially when installed by a GM dealer.

Effective maintenance is crucial; drivers should avoid operating their vehicle when water is detected in the fuel, as doing so can lead to poor engine performance characterized by intermittent power loss, slow acceleration response, and the illumination of a malfunction indicator lamp. For optimal performance, refer to your vehicle’s owner’s manual for further maintenance guidance.

Adhering to proper practices not only protects your engine but also enhances the driving experience, ensuring you get the most out of your Duramax engine. Trust the GM 12639277 Water In Filter Sensor for a performance boost and peace of mind on the road.
