FrostHeater makes custom-fit coolant heaters for Volkswagen TDIs. This model is made specifically to fit the A3 chassis, MkIII Jetta TDI, AHU or 1Z engine codes.
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.
