Part 10 of a longer series on my 1978 Volkswagen Bus electric vehicle (EV) conversion. In this video, I build the coolant circulation system for the water cooled Netgain Controls WarpDrive Motor Controller. This includes mounting a small radiator in the fresh air intake area above the battery and mount the reservoir, pump and lines to create a working coolant system.
