Putting Muzzy aluminum radiator fans on

[Hornfan]

Hey guys...
How difficult is it to change the radiator fans? Do I need to drain all of the coolant and take the radiator off? Anybody know what size the nuts are that hold the fans on are? Just trying to get all of my ducks in a row before I undertake this job, hopefully it won't take too long.

You can sneak the fan out on a gen I Busa without disconnecting the radiator, not sure on a Gen II. Just dont mess up your radiator fins.

just some info i recently put theses fans on while changing my exhaust there are 3 10mm bolts on each
i did not drain the fuilds just unbolted the radiator and oil cooler and let them hang other than its a tight fit it was an easy install

It is not hard to install them but I did not like them. The fans were too loud and noisy.

Easy install..no need to drain anything..
Yes they make a little more noise but they also push more air..on my gen 1 there really not that bad as far as the noise level.

On the Gen I, you need to cut out the green spacer disc. (Not sure about Gen II).
