Electric fan for 2.9 V-6 ?

[ngzcaz]

I just read about power gains for an electric fan kit for the 4cylinder, 3.0 and 4.0 engine. Are 2.9's out of luck ?

same theories apply to a 2.9....believe that they help it if you want to, don't if you dont want to, its your call, you'll get varying opinions on here with no "real" or reliable info to back up claims from either side

i want to do this but noone will help me with what fan to use

I was basically referring to an article in the cooling section of the tech library. I t had to do with an aftermarket kit from Summit racing. Kit at that time was apparently $ 191 and change. While it will probably work, $ 200 sounds like a bit much for an electric fan. And the article was specific to the engines I mentioned earlier. I was curious if anyone had any experience w/it or manufactured their own setup.

there are cheaper ones out there. just make sure you buy one that will move enough cfm's to keep the engine at a proper operating temp. i found one for ~$75 at pep boys, i dont think it comes with a wiring kit or thermostat

you can pick up a nice efan from a junk yard out of2012-13-14 for around 25 bucks

I picked up an efan from a buddy believe I got it for free and just wired it up using a circuit breaker and relay. not sure how much air it moves but my b2 hasnt overheated yet. The way I see it is the 2.9 needs all the help it can get whether it frees up horse power or not it takes the strain of turning a fan off the engine.

i had one on my 3.0, and i could tell a slight diffrence, but i went back to stock, i think i red some where that the tarus fan/shroud works in a ranger...i think

Several have used the Torus fan in their V-8 swaps just because of clearance problems with the mech one.

I think I have a few from newer Explorers and Tauruses because the control modules burnt up. Haven't tried to put them in anything yet.

If you do it, wire it so you can throw a switch in the cab and run it at stoplights, etc., when it's really hot outside...idling in the heat is a killer.

i just installed the summit electric fan on my 4.0 and almost burnt my motor up with it. i use to tow my trailer up the mountians to flagstaff az. with the stock fan clutch set up and the temp dial used to go up to about the L in the normal range this time with the swap the dial went all the way to the red at the H mark so i would have to say it wont work for anybody towing. i called summit and they will give me a refund. so now i am looking into a engine swap just to get some more power to get up those hills.

Just wire it with a relay and direct key power ( on with key..off with key) the factory fan runs the whole time the engine is running, so why not the electric fans? no need for a thermostat to turn it on and off. Unless you want to shut if off in the winter to help the engine hold temps better maybe? I am going to put electric fans on my rangers ( 84 and 87)
just because the plastic blades on my fans are old and brittle. also both rangers have no A/C so I can mount fans in the front also as pusher fans if need be.

I'd like to know the mounting depth on those, too new to hit the junkyards, but might work for some setups...

The fan you used doesnt flow enough air. The taurus e fan flows about 3k cfm on low, 6k cfm on high, its used to cool the biggest of V8 swaps, and fast...

There are different ways to wire one, but running all the time will put a constant load on your electrical system. Wiring it through a high amp rated relay (like the volvo relay) and using a temp sensor is a better way, with a manual override. With the exception of the manual override, this is how most factory setups are done...
