Useful Information

Description and Purpose:

This New Diesel Exhaust Fluid (DEF) Supply Pump Module from GM carries Part number: 23230395. Designed for heavy-duty Silverado and Sierra models, it regulates DEF pressure and delivers fluid through a protected circuit to the SCR dosing injector. Its design supports high-load operation and frequent regeneration cycles, keeping the aftertreatment system supplied with clean, measured DEF.

Why Replacement is Important:

A weak pump causes dosing interruptions; the vehicle responds with dashboard alerts and eventually limits engine output to protect the emissions system.

Impact on Vehicle Performance:

Reliable DEF delivery maintains full torque capability, keeps warning messages away, and helps the powertrain perform efficiently even under maximum towing weight.

Manufacturer Information: 

General Motors® combines modern engineering and strict quality standards to supply components that deliver stable, long-term vehicle performance.
