Do it, I'd suggest independent circuits for all the fans and individual relays for all as well. The big benefit of a mechanical fan with an electric supplement is redundancy. When you have a bunch of electric fans, and you sink your front bumper in a big *** mud hole or cross a creek you thought was a bit more shallow, you run a pretty big risk of frying all of your cooling.
My buddy fried his electric fan on his WJ a few months back on the trail just splashing through some big puddles. But he didn't overheat because his main cooling fan wasn't electrical.
Just realized this is turning into a novel and most likely has been covered before! Cheers. Just some food for thought. Happy jeeping

Skip the PB blaster and Kroil those bolts up for a couple days! Shouldn't need a breaker bar.

I think you are wrong when you say you think it could be better. The shroud and fan/clutch is very very reliable. And that's the key here. Ever had your electric fan go out? Tons of people have. And that mechanical fan just keeps on spinning. I think if you really went crazy, maybe you could do a 3 fan setup that would work better than the factory setup, but you'd have some work in your hands. If you were to

When replacing the exhaust manifold, do I need to replace the intake gasket even if I'm not replacing it, or a good clean should be enough? I will get the gasket for the exhaust part, but can I save some money without changing the other?
Also when putting the new gasket on, I've seen some tutorials where people put a spray on copper coating, Is this necessary or as long as the mating area is clean all is good?
cheers

Right on. I was all sorts of pumped on that dirtbound triple fan setup at one point. Then I saw my buddy very easily fry his fan and my mind changed.

I did what you guys said, cleaned the throttle body, the iac and burped the fuel rail and it runs noticeably better. Thanks guys!
