Ford 6.7 DEF Heater


All modern diesel trucks have a DEF (diesel exhaust fluid) system that constantly sprays into the exhaust system. This breaks down harmful nitrous oxide gasses in the exhaust into simple nitrogen and water, reducing emissions. The DEF heater in your Ford 6.7L monitors the temperature of this liquid and heat it if necessary so it does not freeze, but it is highly prone to failure, sending your truck into limp mode. Our replacement Ford 6.7L DEF heater replaces your faulty heater and gets your truck running just how it should.

• Kit includes all parts needed to replace the DEF heater on your 6.7 Powerstroke engine

• Fits all Ford F-250, F-350, and F-450 diesel trucks from model years 2011 to 2016

• Fixes DEF fault that reduces the max speed of your truck

• Ensures diesel exhaust fluid stays in liquid form for proper engine function

• Our part cleanly and simply replaces factory part with no modifications needed, total installation time approximately 2 hours
