Themo Fan Staying Engaged (mechanical Fan)

[Jay_stylz]

hey guys well haveing a bit of a problem in the past few days have noticed my thermo fan is staying on ?the car sounds like a truck and i noticed the running temp is alot lower than normal soo not really sure what i could be because i know the fan is mechanical and runs from the motor any ideas what maybe causing this?

get a new fan

get a new thermostat

your fan clutch could be farked ... you will notice your fuel economy worsen very soon. New ones are about $220-250 from memory (not Nissan but aftermarket, some joint in Melb iirc sells them) Definately change the thermstat if you haven't in a while ..theyre cheap

before you go buying a new one i think they can be repaired for alot cheaper (viscus fan I mean)

[Jay_stylz]

ahh okay where would i get it fixed?

[Wacky Dee]

I wouldn't bother .. new one is $200 .. easy to remove. It's that big chunk of metal that sits just behind the radiator fan (that spins the fan) - just 4 studs holding it.

ahh k nice any do u mean replace the whole fan ? or?

You don't need to replace the "fan" unless it's broken. The fan is bolted on top of the "fan clutch" which itself sits on top of the water pump pulley ... you just need the "fan clutch".

It's that chunk of metal that your plastic radiator fan is bolted onto ie. http://www.google.com.au/images?hl=en&...330&bih=935

Here you go .. http://www.daviescraig.com.au/Fan_Clutches...65-details.aspx

but that's for R34 GTT .. probably same for R33 but if you want, give them a call and make sure.

EDIT: come to think of it .. I still have my old one which works perfectly, you can have it for $50 and if it doesn't fit I'll take it back. I only changed mine in an elimination process amongst many other things whilst trying to reduce my fuel usage. (turned it was just the coilpacks + 40psi tire pressure gave me a drop from 17l/100Kms to 13l)

ahh k sounds good lol gonna go source one now the car sounds like a truck lol not cool already looks bad enough not being painted at the same time with black side skirts and a grey spoiler lol

yeah was gonna say look for a second hand one or look at getting the fluid inside replaced

dont quote me on this but im pretty sure it was around 50 dollars to get the fluid replaced. Im not sure where to get it done but

This issue can also occur when the coolant temp sensor fails

Some units can be overhauled.
