Okay ressurrecting an OLD post here but seems im having the exact same issue as a number of previous posters... and wouldnt mind some insight on a solution without developing some wizzbang cooling system.

i Own a 93' GTR V spec (newly aquired and i beleive i have the issue where the viscous clutch is permenantly engaged, as reguardless of coolant temp the fan just matches engine speed. so over 5000rpm it is absolutely ROARING, is this just a VC issue? i dont want to risk playing with the radiator myself so is this just a take it to a workshop and have them replace it with another VC? (obviously there could be a host of other issues like a faulty sensor etc?) would a normal radiator specialist handle that or would the GTR be too too complex and i need to go to an import mechanic that deals with GTR regularly?

nothing complex about the cooling system on a 20 year old skyline. it is no more complex than the cooling system on a commodore or falcon of a similar age (especially since it is extremely similar to that of a vl commodore). skylines are nothing special as far as how technical they are. compared to new cars they are old technology.

the only issue your average workshop may have is whether they have something in stock to replace it with.

also, was it playing up before the current heat wave that most of australia is seeing? temps like we have seen over the past week will always put extra stress on the cooling system

If the hub was stuffed and your fan was fully engaged, you will hear the fan all the time.

One way to test it is when the engine is cold, spin the fan by hand. It should turn with resistance, spin about 1/4 way or so then stop.

On cold start, the fan will be engaged for a few seconds then you will hear it go 'off' (disengage).
