I heard they can rob you from a little power too, cause how much air they move especially on a 4 cylinder

This guy I meet this weekend has a 70's Bronco with an Electric fan he's replaced twice from blades braking off from water.  :smack:He said the blades flex forward from the water and pull them in to the fan motor mounting bracket braces and brake the blades off :shake_head:

sounds like that dude need to install a dp dt (double pole double throw) switch in for the fan.  That way he could kill the fans for deep water.  On another note you would think he would learn...kids these days! LOL

I have two elc. fans on my truck, one has a swicth to trun it on/off. the other is on a themal switch, but i think if i went into the water it would shut down fast from the cold water cooling off the rad. unless you just had to "charge" the water.

Are there any electric fans available to strip from a stock vehicle somewhere? Is it even stock on any vehicle?

i had a flex fan come apart on me.  took out my radiator and top hose and went through the hood.  they are noisey and do not cool as good as a clutch fan.

i won't run one again.  

you know the toyota clutch fans can be refilled with the silicone oil.  the bottle costs about 8 bucks from the dealer.  get two bottles just in-case you drip some like i did.

Stick with the stock fan clutch.  No wires, no adapters, works fine lasts a long time.  Tried all the other crap and went back.

I have the black magic fan..Its been pretty good however it was not always that way.I ended up having to use a ford starter solenoid as a relay to keep it running on long trips or times when its on forever..I would not buy one new.There spendy..I got mine chep from a guy and it was like new..The rebuild of the stock clutch is best unless you see your self in deep ass water.No way would I drill holes in a fan..You run a risk of hairline cracks and broken blades and damage to yourself and your rig..Flex fans are for hot rods..Water hits them and the blades will bend bad..So if you don't do damage to your rig it won't cool the same abd your still screwed! :beer:

I have it and am GIVING it away, it draws a waaaay to much! I had to get a hi-output alternator and then I needed an expensive 75 amp relay (like $50) and it still causes issues because it draws so much. I went with a spal for about $80 and it only pulls 8amps!

I am running a flex fan. NP yet. with my set up I still run 150 deg..Crawling on the beach it peaks to 190deg. The fan does flex allot. When I race I can hear the fan flexing so much it hit the engine oil cooler..

Remember I am running flat top pistons a big cam, in my 4.3L..No cooling problems at all..  :beerchug:
