You don't need a zj clutch if your radiator and cooling system are working properly. I took it off and threw it in the parts pile when I put the HD radiator in and put a stock one back on.
Truth.

Dude... the ZJ fan clutch is killing my MPG (from 12.5 to 11). Its noisy as hell and performance has taken a hit too. There's got to be something I can do with an e-fan set up.... if not Dirtbound's set up, maybe something different?
I like the idea of decreasing the parasitic drag by ditching the clutch fan and being able to keep the fans running for a little while after I shut the engine off on a hot day to help with vapor lock.
Any suggestions?
Did you install the new radiator yet?
How old is your electric fan? And not all "stock" electric fans are created equal - the Crown units and the ones from the chain auto parts stores do not move as much air as the factory fans. The factory fans are worth the extra $$.
Yes, the mileage and performance hits are an affect of that fan clutch. It takes horsepower to move that fan.

Sounds like you need to re-gear, too.
These guys are right about you not needing the ZJ fan clutch.
I just suggested it much like suggesting an insurance policy.
Let us know how that e-fan kit works out for ya'... :helpme:
Maybe you have some crud build up in the internal passageways of the cooling system.
I've seen suggestions before to run a vinegar/water blend for a little while to help clear out crud. Don't know about the efficacy of that, though.
