Diesel Exhaust Fluid Header

The diesel exhaust fluid (DEF) header is an important component in the selective catalytic reduction (SCR) system of modern diesel vehicles. It is responsible for storing and delivering the DEF, which is a solution used to reduce harmful emissions from diesel engines. The header typically consists of a reservoir for holding the DEF, as well as pumps and sensors to ensure proper delivery to the SCR system.

Proper maintenance and monitoring of the DEF header are crucial for ensuring optimal performance and compliance with emissions regulations. Regular checks for leaks, proper fluid levels, and functionality of the pumps and sensors are essential to avoid potential issues with the SCR system. Additionally, following manufacturer recommendations for using high-quality DEF and keeping the header clean can help prolong its lifespan and prevent costly repairs.
