Went To Canberra

[Suspense]

Well last nite i went to canberra n back, from sydney.... (highway driving) now i have noticed my engine fan is spinning too fast, on idle i can feel the air its pushing at the back of the engien back, and at 2500rpm the fan is bloody noisy....

How can I fix this? nothing is broken is it?

Sounds more like that it is spinning when it shouldn't. This is because it's a viscous clutch fan, and when it fails, it locks up.

If you start the car when it is dead cold, it should spin up and then come off after a minute.

Or, to test whether it has seized or not, tomorrow morning, open the hood, and try to spin the fan with your hand (car off!). If it resists a LOT, then it's seized and you need to buy a new one. Changing it is pretty easy though (4 bolts), and if you wiggle it, just a little bit, (hehe) it should slide past the radiator shroud.

the clutch may have siezed.

check that you can move the fan freely back and forth with the engine off.

looks liek my clutch has seized... how much is a new clutch for the fan?

[RANDY]

You can drive it as much as you like. It will make a lot of noise from the air being pushed, and it will still cool everything (even when it DOESN'T need it).

New fan I think is under $200... Call Nissan?

[MANWHORE]

Be very very careful. I'd try not to drive it if you can.

There have been guys on this forum with the same problem. When the fan lets go.... I've seen pics with holes in the bonnet. the radiator also gets chewed up.

try not to go to canberra...

if you don't get car problems from it, you will definately die of boredom!

the clutch on it has FAILED dude. this means what it does next is anybody's guess. which means it may loosen at any moment and start free spinning, i.e. not cool your motor.

if you're going to spend $200 on a clutch fan, why not upgrade to an electric thermofan for a bit more. i'll be doing that mod soon.

yeh... need to look around... bloody cars.. time to by a camry

Don't panic....... Pull the fan & clutch off, if you're in Sydney, go see the boys at Just Jap in Kirrawee or SSS in Giraween ( or the like ) and grab a good condition second hand clutch off them !! Just make sure it bolts up to YOUR fan and looks the same ( but better than yours ) and away you go !!!

I was a bit suss on my clutch ( fan ) and scored an almost new clutch off an R34 RB25NEO that fit perfectly in my R32 RB20DET fan and works great !!

[Suspense]

hmm.. now my socket doesnt fit in the gap to take the bolts off... and using a spanner it seems real tough? which direction should i be spinnign the bolts which hold the clutch to the gear.?

[TokyoTaxi]

All the bolts undo counter-clockwise from memory.

i don't know if i'd be going the thermo fan route. i have heard bad things about them on skylines. mostly about them not being able to flow enough air. but this may be due to people not using big enough fans.

[SECURITY]

16" fan should do the trick.

or two 12".

[Suspense]

done.... (picked up some nice spanners to add to my toolbox)... For ppl doign this in the future, don't pull the fan off too hard, you may damage the radiator fins... i came awfully close thanks every1 for your help
