Useful Information

Description and Purpose:

The new DEF Sensor Head Unit from Genuine International/Navistar, Part number: 4097724C91, monitors diesel exhaust fluid levels in heavy-duty trucks. Compatible with a 12-gallon DEF tank and designed for N9, N10, N13, and DT engines (2011–2016), it ensures accurate DEF measurement and supports proper emissions system operation in commercial vehicles.
