Block Heater Kit for 82-84 Diesel Vanagon. This kit keeps your engine warm enough in the winter so that starting should not be an issue. You will need to remove a freeze out plug in the rear of the block and then install this in it's place. You will need to plug it into 110v at night and leave it plugged in all night to get the full effect. Also be sure to unplug it before you drive away.
