What does a reductant tank heater do?
Simply put, the reductant tank heater refers to the heater that keeps the DEF or reductant warm when temperatures are below freezing. The reductant, which is a reducing agent, helps reduce oxides of nitrogen (NOx) within the diesel exhaust after treatment system.
Where does reductant go in a diesel engine?
Reductant (DEF)Injector • The reductant injector is a Pulse Width Modulated (PWM) solenoid controlled directly by the PCM. The injector receives reductant from the reductant pressure line and sprays it into the exhaust stream, where it is mixed into the exhaust gases before entering the catalyst.
How does the reductant system keep Def in a liquid state?
Reductant System Components: Heated Reductant (DEF) Supply Line • Connects the outlet of the reductant pump to the reductant injector. • Is heated by a wire wound around and encased in the line. • Is heated to keep DEF in a liquid state in cold ambient temperatures (below 12⁰F/-11⁰C).
What does the fill level valve do on a Ford reductant?
• The fill level valve is designed to prevent overfilling the reductant tank when using Ford approved DEF bottles. • The tank vent is designed to allow the tank to breath during thermal cycling or during high consumption rates. The vent will not allow liquid to pass into or out of the tank.

What happens when the reductant tank is full?
The reductant is a good conductor of electricity. When the reductant tank is full, the reductant closes a circuit between all three level electrodes and the ground electrode, indicating the tank is full. As the reductant is consumed, the level drops and uncovers each electrode in sequence.
