R32 Gtr Clutch Fan Sometimes Making Spinning Noise

[den001]

my gtr drives very well and i have just done a major service on it,

now after doing the coolant, i have noticed that sometimes when im sitting at lights or sumthing i give it a rev and the clutch fan spins loudly like it need to cool the radiator down more...

other times ill give it a rev and just a sweet rb26 rev, no fan wooooshhhh if you know what i mean,

its about 50% on and off. im pretty sure i bled the system, properly... cranked the heater and had the water level over the top of the head in a special funnel to bleed all the air, but the nipple on the top/side of the head, when i let that out, it was sucking, not spitting water out??????

it was like it was a vauucm line undun, sucking away.... whats the go

any1??

Not sure what you are talking about

Have you tried reving the motor while your looking at the cooling fan ?

maybe the hub for the cooling fan is rooted?

check the hoses for cracks or leaks

I experience the same problem too. If i sit at a traffic light for too long and then accelerate off, all i can hear is the clutch fan over the 26. It also does it after i start it up. Takes a good few minutes of driving before the noise goes away. I Would also like to know what's causing this?

Its normal, depends if the coolant is hot enough to tighten the clutch. It tends to work in cycles, although more often after idling.
