Useful Information

Description and Purpose:

Identified by Part number: 2515990C3, this new Genuine International / Navistar DEF Tank QLS Head equips 5-gallon DEF tanks with Canbus quality sensing, filtration, heating, and fluid delivery in a single 6-bolt module. It uses a 40µ internal filter for clean suction, while its 11-inch heated body ensures reliable cold-weather operation.

Why Replacement is Important:

When a QLS head fails, DEF level, quality, and temperature regulation may be lost, causing SCR errors and restricted engine power. A new module restores sealed filtration and precise electronic monitoring.

Impact on Vehicle Performance:

Proper filtering and controlled heat delivery ensure stable DEF supply to the SCR system, protecting fuel economy, torque output, and emission compliance even in low-temperature environments.

Manufacturer Information: 

International® designs parts focused on dependable performance, supporting efficient transport operations.

Navistar® manufactures quality parts that help ensure consistent operation and reliable vehicle uptime.
