Flex-A-Lite Mojave Heater Install - Adding Heat To A Cool RidePosted in How To on June 1, 2010
When we added some big shocks and shock hoops, we had to ditch the blower motor and subsequently lose all climate control in a removable top K5 Blazer. This was fine most of the time in Southern California, but when we started crossing state lines and hitting snow during off-roading trips, a heater was a sought-after item.
When we got home, the first call we made was to Flex-a-lite, makers of the Mojave Heater. We had heard of these little units forever but hadn't actually tried one yet. Our lack of knowledge on them led us to believe they were completely electric, but when we opened the package we found that we still needed to run heater hose lines to bring coolant in and out of the cab. This made our initial installation plans a little more difficult, but we realized that the amperage load that would be necessary to run a purely electric heater would be more than running multiple air compressors. Therefore, the electrical hook-ups on the Mojave Heater are for the fan motor control, while heater hose inlet and outlet are for supplying the heat.
As soon as it was installed and we had our vehicle warmed up (remember that the warmth comes from your engine coolant), we switched the Mojave Heater on and were blasted by some heat waves.
