Modifying the Viscous Fan

[reintel]

Had little trouble with my viscous fan since it has too much freeplay. Decided to replace it with new parts.

I was looking at the old viscouse fan and as we all know, unlike Toyota or other brand viscous fan where you could actually top up oil, or reconditioned it. Nissan one, we normally have to dump it away. I was thinking, if i bore a small hole to fit a screw and fill it up. Will this actually work? I notice that the front coil has a oil leak and perhaps i weld it down and lock the thing up so it will spin full time?

Will this work? Off course I will do the testing, but perhaps some opinions will be much appreciated.

faced with the same problem last time ... but managed to find oem replacement ... which cost me quite a lot

if u want, i can ask my mech to source one out for u

The safest and easiest for you, change a new one!

 

[reintel]

I've replaced mine with a new set. Yes it cost a bomb. But I was wondering to modify the old one so it will turn faster or perhaps locked it down using silicone as normally use on 4wd viscous fan.

i see ... it is best for ur question to be answered by tech guru mate, as for me, i dont really fancy tampering with the oem stuffs

Did anyone here ever consider electrical fan ?

If you manage to lock the Viscous fan, won't that create the constant noise from the fan ?

 

[reintel]

Noise will be definitely be there. The other option of using thermo fan/ electric fan is that it may not be able to blow as good as using viscous fan. Unless using 8 blades 16' SPAL or 2 units of 12' fan.

The other problem is to custom made the shroud fan for electric or it wont work well. Must use pull fan and not push fan.

Advantage using electric fan is that the engine feels a bit 'lighter' and rev better. Downside, if constant high rpm, temp will increase.

 

[K20AEK]

Some electric fan does have these step stage of increment of speed depending on certain temperature. correct me if i am wrong.

My friend recommeded me one article on this eletric fan setup, i would love to post the link up the website has been down ... this is what left of their research ..

Speaking of fans, just wondering if anyone ever sourced just the blades for RB26, whether they are brand new from nissan, aftermerket or from chopshop?

I do! Aftermarket ones.. why? You're not talking about the ceiling fan are you?

I would like to know where to source this too.

 

[reintel]

Chop shop(If u can find) - RM200-300
New - No idea!

Normally they sell in set. Roughly ard RM600-700

I don't know about locals but internet and Japan, there are abundant. RHDJapan is one of 'em.

I quote:

Billion super electric fan 12" Rm700++
"Diameter : 327mm
-Thickness : 80mm
-Flow Rate : 428L/sec
-Power : 100W

-PULL
-PUSH

The push types are mounted in front of the cooling core and push air through them. The pull types mount behind the cooling core and pull air through them. These fans are capable of increasing your vehicle's cooling power because of their high flow. Can be used in the narrowest spaces due to the skinny design."

Yeah, got the 1962 KDK 4-blade ceiling in mahogany :hmmmm:




No, seriously ... Anyone got the replacement fan for the RB26? Those useless plastic one tend to crack, chip off and who knows what tikus makan them or something wor ...

 

[cosmicgate]

plastic ones if they crack i get the rm3 elephant glue and they work wonders. To combat vermins i get NVMRC party deathbot from mousehunt on facebook and they operate on 6 AAs batteries and work round the clock, no complaints so far from me. Biggest catch was a 22lb mouse trying to nible on crankshaft sensor feed, hah nice try mouse!

I see you may own one of those annoying rat-dog but then again, 22lb makes one massively overweight pet :hmmmm:



Anyway, I have lost a couple of blades on the fan itself. I guess no matter how much glue would not fix it, nor KDK fan blade either.

Reintel, once again....go get a new one and this will solved ALL your problems and time. Best of all, you will have a peace of mind cruising it down our "nice and smooth" roads.....

S-Tune,
Dont worry. I've already get my boyz to order 1 full aluminium radiator for me. Will take a month or 2 to get here.

However I got few good experience.
1. R33 GTR radiator is shorter by 1 inch at the bottom and fan shroud is smaller.
2. No point to dismantle the top cover from a 2nd hand unit as it will break due to stress from age and unexperience worker.
3. Never trust OSAKA radiator worker and boss. Talk cock only. As if I'm begging them for help. Inexperience, bullshit and low quality products.
4. RB engine require better coolant to work. Recommended Redline Waterwetter. (Semperfi, if you coming down to KK, help order for me 3 bottles!)
5. Philipine gam(glue) is really strong!!...
