5502-17 DEF Heater Control Coolant Valve for Kenworth & Peterbilt | ATP USA

Keep your emissions and aftertreatment system functioning reliably in sub-zero conditions with the Advance Truck Parts (ATP USA) 5502-17 DEF Heater Control Coolant Valve. Engineered as a direct heavy-duty replacement for OEM 5502-17 and F90-6016, this 2-way 12V solenoid accurately regulates engine coolant circulation to the DEF heating loop, preventing fluid freezing and crystallization in cold operating environments.

• Direct OEM Fit: Engineered to match factory mounting brackets and electrical connector configurations for straightforward installation without harness alterations.
• Heavy-Duty Construction: Built using durable, thermal-resistant housing materials formulated to withstand engine-bay heat cycling, road vibration, and environmental contamination.
