ACDelco 84412928 Diesel Exhaust Fluid DEF Tank Reservoir Kit

The ACDelco 84412928 is a genuine GM original equipment diesel exhaust fluid (DEF) tank reservoir kit designed for GM trucks and commercial vehicles equipped with diesel engines. This emissions reduction fluid tank assembly is a complete replacement unit that includes integrated temperature and level sensors for accurate DEF monitoring.

Key Features:

• Genuine GM OEM part engineered specifically for GM diesel vehicles
• Complete reservoir kit with integrated temperature and level sensors
• Designed for diesel exhaust fluid storage in SCR emission control systems
• Helps reduce nitrogen oxide (NOx) emissions by delivering DEF to the exhaust stream
• Direct replacement for worn or damaged DEF tanks
• Manufactured to GM's strict quality and durability standards

Diesel exhaust fluid is a critical component in modern diesel emission systems. The DEF tank stores the urea-based solution that is injected into the exhaust to convert harmful nitrogen oxides into harmless nitrogen and water vapor through the selective catalytic reduction process. A properly functioning DEF tank with accurate sensors ensures optimal emissions control and prevents vehicle speed limitations that can occur when DEF levels are low.
