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.

can it still eb driven until my new fan arrives? and where to get a new one? how much?

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?

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.

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 !!

    • Oh, also, forgot to add these photos I believe.
    • Thought i'd update on this. I was able to get in contact with Craig Lieberman and later on Darryl Alison (owner of Kaizo Industries). Darryl was able to help me verify that my car was in fact one of theirs and is helping me find more info on mine !
    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
