Fan Problem HELP

[ZERO]

i just gave my 33 a little fang up the street with a on spot u-turn and wen i got to the end of the street i notice that there was more noise coming from the engine bay... it seems like the fan is working harder or spinning more if that makes any sense... it is normal when the car is idling but if the rpm rises so does the fan noise or the fan rpm.... just sounds like this massive V8 roaring down the street with a huge as fan... not a rathered refined 6cyclinder turbo...

i didn't know wat to search for so yeah sorry guys...

AFAIK, the fan on R33 has a viscous type centre, so the fan should only work when the centre warms up. these centres can die.

As an option (if you have the dollars, I dont know how much a stock fan will cost) buy a twin thermo fan set up from a dismantler, and have that fitted instead. It will need to be adapted, but will give you more power (less load on the crank) and better cooling.

they can be bought from as little as $85 dollars, perhaps less. Go into a radiator shop, they should be able to hook it up with a thermostat to only run when the car gets hot.

so when idling even though the engine hasn't warmed up the fan should not be spinning?

[TTT]

the fan always spins.

the skylines have what they call CLUTCH fans.

it should spin faster with the revs when it gets hot.

It is normal for them to seize up.

You can get a scond hand one from the wreckers for $50 or a brand new one for $150 (these prices are for the clutch part only)

when asking for it, you need to ask for a VL commodore one.

they are identical.

Thermo fans are the other option but it requires some fiddling to get them fitted properly over your radiator and connect up a thermostat and so on.

There are only 4 bolts to take off to remove the the whole fan assembly off your water pump.

then another 4 bolts (I think) to take the fan off the clutch.

oops, my bad, sorry about that they do run when cold sorry about the bum steer

[TTT]

they run but they are sort of passive.

the fan always spins, but when it gets hot, the fluid in the clutch bit makes the plates grap and it turns as fast as the crank does.

normally, when it's hot, you accelerate and you can hear it howl with the revs until about 4000rpm, you hear the fan sound die down.. but it still spins.. just not at the same speed as the crank.

HI guys, make sure the fan can be turned by hand when the engine is off. If not, the clutch is seized, it happens a lot. Grab one from your local dismantler.

[ZERO]

yeah mine can be turned BUT WITH SEVERE FORCE and only abt 3 cms each way.... so i guess that means that the clutch fan has chucked in ay... damn... there goes another $100 wasted... would've been good to use that to buy a case of beer for u guys... thanks heaps for the help!

[TTT]

I still have a spare brand new one at home..

I payed $150 for it if you are interested.

[ZERO]

umm...

what exactly do i need though? just the clutch parts?

150 is that fitted?

[ZERO]

ill check out some dissmantlers first and ill let u know can't really afford to buy anything brnad new atm.. just need it to be fixed...

but thanks for the offer...

[TTT]

Yes you ONLY need the clutch part.

If you want, I can install it for you.

It's pretty damn easy..

let me know how you go.

[wrxhoon]

hey gtst do u have the actual fan as well ? or just the clutch part ? if u have the fan i'm interested .

[TTT]

no I don't have a fan.

just the clutch.

the fan will cost you next to nothing from wreckers.

[ZERO]

HEY GUYS I JUST BOUGHT A FAN CLUTCH AND THE FAN.... and bloody ell before i got to fit it on my original one started to loosen up and work agian... well after i lubed it... now i got a whole fan clutch and fan sitting here.. bought for $80 second hand anyone need it?

[TTT]

Keep it dude..

your one will fail again.

I guarantee it..

you may have lubed it but it's the clutch thing on the inside which you can't get to that fails eventually.
