FrostHeater makes custom-fit coolant heaters for diesels. This model is made specifically to fit the 2011 to 2025 Ford Super Duty 6.7 diesel

The FrostHeater connects to the vehicle's coolant system, heating the coolant and the engine block. Pre-warmed engines start faster and give cabin heat much more quickly.

Plug in the FrostHeater a few hours before you leave for a better start and quicker heat. Plug in for 4 hours and enjoy a fully warmed engine and instant heat in the cabin. Even better, use a heavy duty timer that turns on the FrostHeater for you.

Installation instructions included.
