Useful Information

Description and Purpose:

This Genuine DEF Level Sensor for 15.5, 16, and 23-gallon tanks. Brand: International / Navistar. Part Number: 2515985C3. Condition: New. This heavy-duty truck component plays a key role in monitoring Diesel Exhaust Fluid levels within SCR aftertreatment systems. It uses advanced QLS and SSI signal technologies to ensure reliable fluid measurement across varying tank sizes.
