electric fans don't last near as long as a fan clutch. I've replaced the rover condensor fans multiple times, even with flex a lites once. flex a lites didn't last more than a few years. OEM stuff lasted at least a decade, but still crapped out.

The mechanical fan on my cj bent when i went through deep water and went into the radiator. Congrats on your expert level number of water crossings bra!!!!! Great accomplishment!


I looked into electric fans for my 6.4 for awhile and kept getting turned away. The mechanical fan is always working, always pushing a constant stream of air across all coolers. The E- fan, will kick on and off at a certain temp but often with a truck that is towing, it hits these temps while pulling a steep grade, once the fan kicks on the temps are continuing to skyrocket and the fan can not keep up. Meanwhile the stock fan would have been working to lower these temps from the start, getting a "head start" on cooling compared to an electric setup.

Hope that made some sense.
