Kenlowe fans playing up

[V8MoneyPit]

After a bit of serious muddy water at the weekend, my twin Kenlowe fans have decided to stay on permanently. On the way home the warning light for them was flicking on and off all the time, even though the temperature was nowhere near high enough. Now they come on as soon as I switch the ignition on.

The thermostat is mounted high up near the top hose just under the top of the LH wing. It did get a bit yucky and I assume there is a short in it. So I'm hoping it will sort itself out as it dries out! Hosed the engine bay down today, so it's wet again now  :D , but I'll see what happens later.

I have a manual switch to isolate the fans when wading, so I am leaving them off until it gets hot. The really odd thing is that when I switch them on the engine slows and runs rough. That bit is a little worrying. Any ideas anyone?

Sounds like they're taking a lot of current, and the alternator's having to work overtime to keep up...

Once the electrical "moving" parts - I assume it's all PCB's - are clean and dry, I would have thought normal service would be resumed.

Mud and water can be quite efficient at shorting PCB's...

Thanks for your suggestion. Hope that is the case  :? I may have to cobble up (sorry, carefully fabricate!) a shroud for the thermostat. Or maybe some more liberal spraying of chain grease!

Can't remember who it was who suggested motorcycle chain grease as a water proofer, but it certainly works. The V8 dizzy cap has been sprayed with the stuff and it started on the button after washing the engine bay. It would never have done that before. Thanks whoever you are  :lol:
