For my WJ, I removed the electric fan entirely because the relay kept failing, even after replacing it with a brand new relay four times. I still don't know why that kept happening. I replaced the electrical fan with a beast of a mechanical fan, an 11-blade viscous-clutch fan. The only way to remove the fan shroud (which is what the electric fan mounts to) is to also remove the mechanical fan, sadly, as far as I know. To make things easier, I only have the fan shroud attached by the top two bolts, and it stays on absolutely fine with no vibration or anything. It's nice not needing to worry about electronics failing now... the fan just always runs when it has to, and worst-case, the clutch is the only thing that can fail, and if it does then it will just be stuck on full blast all the time which is literally fine lol.
If you're interested, here's the setup I have for the mechanical fan, which is guaranteed to keep the engine even cooler than the electrical fan ever could:
The fan blades
The fan clutch
You'll need to get from your hardware store: four m10x1.5x12mm bolts. My hardware store didn't have any of that exact length so I had to get 25mm length and just cut them down to 12mm. Pretty easy with a Dremel and cutoff disk.
If you have any other questions, feel free to respond to this comment. I highly recommend upgrading to the proper mechanical clutch fan setup if you're having issues with cooling the engine. For under a hundred bucks you can make the upgrade using the Amazon links above. Hope this helps!!
