Disassembling viscous fan

They look rather nice. If they will run at 12 Volts, which I would think
they will, a rough calculation current wise is to double what the 24V current
rating is for 12V use.

Something to do with a slash?

i would say so....

Made me head hurt looking at that link, i'll just wire it to a 12v battery and see how it pumps (if at all), they must be pretty sturdy bit of kit to cope with the long engine hours and temps of a PSV

[MattF]

You had chance to try one yet Ian?

[POPEYE]

No mate, afraid not, where does the time go! a mate was round weekend doin some plastering for me and spent today s$$$$eing it off the floorboards,
Apart from wipping the air filter of the truck to see if it runs better i aint even got time to wash it, prob be after christmas before i can get going on the truck

A 50 hour day wouldn't be long enough to fit everything in, would it.

Mine appears to be okay on the cooling front now, since I removed what was
left of that brass adaptor. Well chuffed with how tight that temp switch is
keeping things. Normal running, without giving it welly, the Surf will keep itself
cool. As soon as it goes above normal temp, however, the fan kicks in. So
idling at junctions, or giving it a bit of welly up a good hill, the fan kicks in
fairly quick. Haven't seen the temp go above mid to high eighties once yet.
The true test will be next summer, though. Just trying to decide whether
to try put a speed kill switch on it. To keep the fan off at speeds above 50
mph, for example.

Thats good news then, this is summat i definatly will do, mines getting into the ninetys now and if i cane it the temp goes a little higher (unless i switch the fan on of course) i've run it several times now without the air filter and it's definatly better (along with that screw adjusment) so i'm getting a full set of filters for xmas, Well she said what would you really like! she thinks im nuts but its better than underpants

A pic of where I've mounted the relays for the fan:

Nice neat job Matt, like to see tidy wireing,

is that a horn attached to the firewall (or are you just pleased to see me)

Two horns actually. I'm doubly pleased to see you. Yup, they were
the standard horns when I got it. On a bouncy metal bracket mounted by
the fuel filter.

Now that I've left it long enough that you all thought I had let this thread die........... Still running strong with the electric fan in place. According to the after market gauge, not once has it gone above very low nineties, even doing some nice runs up good hills at a decent speed and revs. Fan kicks in fairly quick when sat at junctions or suchlike for more than 20-30 seconds, so it appears to be doing the job rather well. Haven't found any more scuffing on the motor casing either, so it appears that extra 1/4" clearance from the front of the pump did the trick.

There is one more small question, however. Does the viscous fan unit act as a ballast/dampener to a small degree with regards to engine vibration?
