Anyone running e-fans / disconnected fans clutch?

First of all, Happy New Year to my JG family!!


Now, being of work for two weeks enduring the wettest weather ever sucks. However, it does give you time to research stuff - especially now I have a cold.

So, I already had cams in my mind but now I am dreaming of lumpy idles. Stall converter is added and now onto what might be the cheapest one - an e-fan conversion.

WJJeeps mentions: 'Remove clutch fan + short belt PS/alternator bypass' to free 10 horse and 17 torqs which sounds good.

However, what exactly do I need to do or buy in order to achieve this? I am only interested in the remove clutch fan so I know I won't free that much power but should gain some, right?

I forgot exactly but I do recall the V8 fan being electric and driven? Can I simply disconnect the clutch and it will remain electric and turn on when required... Or do I remove the stock fan completely and fit an e-fan instead, if so any kits out there?

If anyones done this I'd like to hear your experiences.

Thanks in advance as always.

You don't have the hydraulic fan driven by power steering? Maybe they did that different on exports...

Anyway, the fan is either mechanical, driven by the belt and a clutch, or it is electric motor driven, or hydraulically driven by power steering. If you have the mechanical clutch fan you can probably find a generic model electric fan to put in its place, or maybe a fan from a newer GC would fit yours, im not sure.

Yes, that's what it runs off. I knew it was either the PS or Water Pump.

Both setups are identical.

Wait... It can run off all three!?! It is possible to disconnect it from the PS and WP and keep it electronically driven controlled via PCM/BCM?

No, it is only 1 of 3. The electronics control speed by way of a valve, there is no electric motor to spin the fan.

Re: Anyone running e-fans / disconnected fans clutch?

I think all 4.7s had the hydraulic fan and no e fan at all.Look at your water pump pulley. If there is nothing physically attached to it it's the hydraulic fan.Sorry Marty but there is no performance to be gained with this fan setup. It already runs independently of the engine.I doubt they would delete that on the exports.

Re: Anyone running e-fans / disconnected fans clutch?

Thanks for the explanation of how exactly it works guys. I thought it had a built in motor, but now realise it is just an electric valve. Learn something every day on here!

It looks exactly as you describe Dave.
