The Flex-a-lite Mojave heater is designed to simplify the task of providing heat and comfort to your ride. It eliminates the need to locate hard-to-find parts, or go through expensive rebuilds to get old units in working order. The Mojave gets its heat from the hot water in your vehicle's cooling system (just like an O.E. unit), but has the advantage of fitting into a wide variety of confined spaces. Its compact size, ease of installation and operation make it the ideal replacement unit.
