    Complete, Compact Heater Unit

    The Flex-A-Lite Mojave heater is designed to simplify the task of providing heat and comfort to your Hot Rod, Jeep or Utility Vehicle. It eliminates the need to locate hard-to-find parts, or go through expensive rebuilds to get old units in working order. Its design offers several mounting options, and the optional Plenum includes adjustable louvers and a flange for defroster ducting. The Mojave gets it 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.
    Its size is ideal for street rods, pickups, and customs where a smooth firewall is desired.

    Rated 4 out of 5 by from Cheap and easy. Nice little fan coil unit Bought for my car because I had removed the factory AC and heater core. Wanted some quick heat for the winter. Works great only drawback is the fan is noisy which is only a problem for people with quite cars,my cars exhaust cover the noise.
