FrostHeater makes custom-fit coolant heaters for Volkswagen TDIs. This model is made specifically to fit the 2012+ Passat TDI sedan with the DSG automatic transmission.
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.
