Some old mand can up to me at a gas pump and asked about my snorkel. He asked me if I had a disconect for my fan. He said it would cut down on water getting thrown all over the engine and that it was fairly easy to install. Anyone ever do this? |

I rigged up one of those covered toggle switches to mine (like the Rice cars use for nitrous arming). Yes, it is easy.
I definitely recommend a covered switch that cannot be turned on accidently. |

Where did you tap into the fan circuit? |

I actually fitted an aftermarket fan - this was on my Defender.
You can just tap the main power line, easy enough. The only thing is that the toggle switches are normally open when the cover is closed - you have to flip things around so that the circuit is normally closed with the protective cover down. |

I'm assuming that we are talking about a D1 here. If everything is working correctly, I don't think that you need to wire in a cut off the fan.
Your 'old man' was thinking about the direct drive fans that are powered off the pulley. Most jeeps are rigged this way.
A D1 has two electric fans in front of the radiator and a viscous coupling fan behind the radiator. The electric fans cut on and off based on engine temperature. Normally, the viscous coupling fan provides sufficient cooling power. The electric fans only come on to supply a little extra cooling. The fans come on automatically when you turn on your A/C.
If you turn off your A/C, the electric fans should cut off in a couple of seconds. The viscous coupling fan stops automatically when it hits the water. This is one of the real beauties of owning a Disco. It just works!
Thanks,

Mike is right, from my understanding you don't need it for your disco. |

That it too good to be true...

It's pretty simple really, the viscous fan stops turning when the blades encounter the water. Think of a viscous fan as a friction driven fan only with fluid providing the friction. When the blades hit the water, the viscous coupling is not strong enough to overcome the drag caused by the water and the fan simply 'free wheels'. Once you pull free from the water, the fan will spin right back up to normal speed.

That's great info.
Are D90 fans different than a D1's? Because I remember watching my friend put his D90 into a deep water hole and hearing the fan blades snap off one-by-one launching into his radiator.
Needless to say, a dual fan Hexalite was installed on his truck shortly thereafter. Complete with dash-mount shut off switch. |
