viscous fan, how 'hard' should it be

[andrewlee31]

basically as the title says, on magnums surf the fan coupling will give about 3 blades turn on a spin by hand. and seems to give a good airflow. but not having mine outside to play with, how hard are yours. need to get to the bottom of his over heating, need to see a video of him attacking stanage edge at the weekend

Stiff when stone cold as Phil's is, and free-wheelin' with a hot engine.

Shouldn't that be the opposite way around Vince?

wonder if kenlowe do a fan to fit the surf rad? viscous fans rob the power anyway.

Don't. The Kenlowe fans can't cope with the Surf except under standard driving conditions. Throw any towing or lots of hills into the mix and it'll not be a happy chappy. Plus, what you gain from losing the deadweight on the waterpump, you get robbed from the alternator by the electric fan. The freeing horsepower thing is bunkum.

You would have thought so, but reading this thread....http://hiluxsurf.co.uk/forums/showth...t=viscous+fans
apparently not.


p.s. I don't want to correct Nifty Nev, as he's never wrong!





p.p.s. My fan spins all the time you know, even when submerged in a river!

noticed when i've been playing with landys (i know, dont pick on me im simple) that the kenlowes that are wired in properly to a stat are off a damm sight more than they are on, and actually doing the job properly. probably 80 percent of them are just wired into the ignitions though, and then an utter waste of time.

have i missed something, you been out in the mud vince??? knew we'd convert you, throw away that bucket and sponge, the paint can and the autoglym stuff and come and play

See the RTTH photos!

Best thread on viscous fans is here. (Old Blue's on there, btw). Terry did a lot of experimenting with a spare fan, and did an indepth writeup on its operation.

Wired into a thermostatic switch as they should be, they will be off except under stop/start driving and when you're pushing it a bit. Main problem seems to be with the Kenlowe's themselves. If you check the archives, I can't honestly recall one person who has fitted a Kenlowe on a Surf and still has it on. Making a fan setup from donor vehicles, yes, that should work, but the Kenlowe I would avoid like the plague, personally.

I've got an electric setup on mine, and it's made sod all difference to fuel economy or anything else that I've been able to tell.

just trying to think of a better way to keep his rad cooled, can't give him any more power, he's flat out phil already!! im pretty sure his gas test will come back negative, then its back to square one..

personally i hate bars leaks with a passion, but im sure he must have a pinhole leak somewhere if its not the head.

If anyone from your end is out this way at all anytime soon, I have a dual fan Jag shroud and fans that you can have if you want to experiment with an electric setup. It will need some modifiying to fit, but if you want to give it a shot and see?

With regards to a possible leak, that really could be any of the hoses. Rad cap and rad are obviously out of the equation, so that only really leaves hoses or matrixes.
