Good To Know

Q: Why does diesel exhaust fluid require a dedicated heater? A: Diesel exhaust fluid freezes at approximately 12 degrees Fahrenheit, meaning a heater is necessary to keep the fluid liquid for emissions reduction.

Q: Can a bad DEF heater cause my vehicle to enter a no-start condition? A: Yes, a faulty DEF heater can trigger a countdown timer that eventually prevents the engine from restarting if emissions faults are not resolved.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
