electric fans are good. Id like to swap. But IMO nothing beats the cooling capacity of the viscious. wish i could get another standard fan shroud. Mine is cracked and melted and looking well dodgy

I spoke to a auto elec/mechanic about the fan story, he gave me a good idea, he said he would run 1 fan all the time and the 2nd from a temp. switch.
He also said that a car running too cold is just as dangerous as a car running too hot.
My car was running in 2 stripes and a little bit when it was hot with the viscues fan and the same now, only diffs is my car gets to that temp faster and as for the oil, I recon I'll put in GTX RS witch is W5-W60 that can handel the heat and cold...then I'm covered.

those cases sounds painfully familiar... anyway about the water pump - I have said this in the mailinglist. Nissan asked me sumn like R1400 or 2400 or someting jags, then I risked my ass to go to a parts shop in town that mainly caters to taxis and got a flippin box shape sentra CA18DE water pump for R100 plus VAT - brand spankme new. I had to jippo it a leeeetle bit to get on (buy one of them long thin stick-file thingies and take it easy to adjust holes and so), but it even looked better than the one i had on. BIG price diff.

What place was it? Eddies spares maybe?
I should go there maybe I can get some New replacement parts aswell. LOL
If it works it works!!!!!!

Most parts we need are the same as other nissans like the sentra and sti's, all you need do is take a sample and tell them to mach it, 95% of the time you will get what you need at a very good price. For example, Nissan timing belt R370 Midas match R 116, save baby save!!!

Great Idea! the only problem I have with that is usually taking something off my car means I cant drive it to Midas for them to check it. Bugger

I have that same problem. Its a pain in the ass! and nobody seems to understand that.
My waterpump came from autozone, it was for a skyline and was identical to the original item. Been on now for 9 months +- 17 000km and no problems (with the waterpump anyway)

I feel for you guys, but you know, I don't think getting a lift from someone to get a part could be so difficalt, use public transport!!!!!
Just fooling around with you guys, luckily I stay not even a block away from Midas, the problem is if I don't know how to take a part out, I end up driving to someone I know can help me.

can one actually fix a viscous clutch? i havent fiddled with mine (except taking it off and putting it back on)
what actually breaks on it, stopping it from clutching?
maybe its just stuck or dirty?

Just try Toby??? He has replaced, but may be know more.

viscous fan is filled with a liquid that behaves in a way thats different to most people's experience - it gets more viscous the hotter it gets.
when an engine is cool for instance, the liquid is not very viscous, more like water. it therefore offers little resistance to the two plates that are on each side. so the fan blades dont move much at all while hte engine is cold.
as it warms up if offers more and more resistance between the two plates, and therefore transfers more torsional energy to the fan blades the hotter it gets.
so it works like a ratio then - the hotter the engine, the more the blades spin!!!!
similar theory to a viscous limited slip differential which can also be found on our s13's.

Hands up! I ve got one of hose on my sx

Slowly now Veecee. Come again. How does the viscous material get hot? Is that via the axel running from the engine to the fan then? I mean how does the liquid get its heat from?

he's got ho's

in different sx codes (s13, s14)!!!
ok - corny i know!!!

chemcool - i guess there is a lot of heat transfer from the shaft on the water pump, but there will also be a lot of heat transfer from just being in the "virginity" of the engine!!!
i dont think its extremely technical, like a specific heat source - but i reckon its gets "hot" enough to provide less slip just from being near the engine!!!
i dunno for sure - its a deduction watson!!!
