ACDelco 84412925 Diesel Exhaust Fluid (DEF) Tank Reservoir Kit with Heater

The ACDelco 84412925 Emissions Reduction Fluid Tank Reservoir Kit with Heater is a genuine GM Original Equipment component designed for diesel vehicles equipped with selective catalytic reduction (SCR) emission control systems. This complete reservoir kit stores and maintains diesel exhaust fluid (DEF) at optimal operating temperatures to ensure proper emissions system performance.

Key Features:

• Integrated electric heating element prevents DEF from freezing in cold weather conditions (DEF freezes at 12°F/-11°C)
• Designed, engineered, and tested to rigorous GM standards for reliable performance
• OE-quality construction ensures proper fit and function on GM vehicles
• Complete kit includes reservoir tank with factory-installed heater assembly
• Maintains DEF within optimal temperature range for effective NOx emissions reduction

This genuine GM part (formerly branded as ACDelco GM Original Equipment) is specifically validated for Chevrolet, Buick, GMC, and Cadillac diesel vehicles. The integrated heater ensures that DEF remains in liquid form and ready for injection into the exhaust system, even in freezing temperatures. Part number 84412925 replaces worn or damaged DEF tanks to restore full SCR system functionality and maintain compliance with emissions standards.
