MOPAR 68085908AI DEF PUMP AND HEATER ASSEMBLY FOR 2013-2018 RAM 2500 AND 3500 6.7L CUMMINS
The Mopar 68085908AI DEF pump and heater assembly is a genuine OEM emissions component designed for 2013-2018 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins turbo diesel engine.
This assembly circulates and heats Diesel Exhaust Fluid (DEF) within the SCR emissions system to help maintain proper DEF flow, prevent freezing in cold weather, and support emissions compliance.
A failing DEF pump or heater assembly may cause DEF warning lights, SCR system faults, limp mode conditions, heater circuit codes, poor DEF delivery, and reduced engine performance.
Manufactured to Mopar factory specifications, this unit is designed for direct-fit installation, reliable communication with the ECM, and dependable operation under heavy-duty towing and work conditions.
