Useful Information

Description and Purpose:

This Genuine GM Diesel Exhaust Fluid (DEF) Supply Pump Module is provided in new condition under Part number: 84416299. It ensures the DEF tank delivers steady, pressurized flow to the SCR injector, using internal filtration and sealed connectors to minimize crystallization and pressure loss. Intended for 2017–2019 Silverado and Sierra HD vehicles, it maintains clean, uninterrupted supply during heavy hauling or urban stop-and-go duty.

Why Replacement is Important:

A weakening pump disrupts dosing accuracy and can trigger fault codes that limit vehicle output; replacement prevents derate and costly service interruptions.

Impact on Vehicle Performance:

Restored pressure and DEF delivery allow emissions controls to work correctly at full load, helping the vehicle retain reliable torque without power restrictions.

Manufacturer Information: 

General Motors® continues its legacy of engineering excellence with components that offer durability, efficiency, and consistent functionality on the road.
