Hi,
just been on a 40 mile round trip, running temp was past its normal temp posistion.
when i stopped i immediately checked the viscose fan , and it turned exactly the same as when its cold.
is that right.
i have recently changed the head because of over heating ,bought a new radiator and loads of bits of pipe. took the thermostat out and drove it for a few days , and the water rushed through the system , so the pumps ok. thermostat opens properly to.
cheers.
lozrob.
Once the engine reaches
Once the engine reaches above operating temp, the fan should lock in. I don't know what temp this is, but since you are running hot and it hasn't locked in, I assume that the viscose part of the fan has malfunctioned. These are expensive to buy, but I have seen some second hand ones on Ebay now and again.
Hope this helps.

Assume you refering to a Fourtrak.
You can just dismantle and rebuild, inserting a cardboard section in the vane/oil area to lock up the fan,( posts are on site re this method) or go down the drill and bolt method ( think about the balance of fan unit , as to wear on the water pump bearings). But I would suggest trying the replacing the fluid method. Lots of post on site ( use the search box to the left of this page) re this problem.
And yes I have a over heating problem and have to drive with this in mind, though just in motorway driving, aggressive at 60/70mph plus, though the girl was not built as a motorway cruiser or for this style of driving. So I keep an eye on all posts re overheating re Fourtraks.

DO NOT DRILL AND BOLT
there is a thread on here about stripping and rebuilding the viscose fan i have done it and i think it tooh 20 mins to do you will just need some silicone oil from a model shop as its used in rc cars for the shocks and diffs...i will search and try to find the thread just dont drill it its not nessesary

Fan problems
I was about to suggest this link, but found ' RRW900' had beat me to it, a pretty detailed explanation for the rebuild of the fan unit, this post should be made a sticky or whatever, brilliant work by the guy concerned.
As an alternative, electric fans are available for the Fourtrak. Kenlowe, http://www.kenlowe.com/fans/consumers/fans02.html#no5 have supplied a few and detail them on their web site.

and locked up the fan that way,
