Why diesel exhaust fluid becomes a cold-weather operational problem for trucks
Diesel exhaust fluid freezes at 12 degrees Fahrenheit, and that basic chemistry can turn into a real-world operational problem for trucks relying on SCR emissions systems in extreme cold.
Key Takeaways
- DEF freezes at 12 degrees Fahrenheit, which can disrupt SCR emissions systems.
- Frozen DEF can trigger faults, limp mode, or restart restrictions in trucks.
