VW Bus with Xtreme Engine Heater Living high in the mountains of Colorado, the weather gets very cold at times, making it hard for my 1970 VW Bus to start up in the mornings. After I installed the Xtreme Heater in the engine compartment, the Bus starts up every time. It works much better than the block heater I was using and uses very little wattage. The Xtreme Heater is a must for anyone owning a vintage Volkswagen in the cold.
