I just installed mine on Friday. If I remember correctly, you have to remove both side fairings, uninstall the three main bolts that support the radiator(Keep in ming to be extremely careful not to damage or bend the fins of the radiator), next step is to remove the mounting bolts for the cooling fan. Finally, remove the three screws that hold the fan on the fan motor, replace the Muzzy fan and that funky gasket that they supply you with. Their instructions confused me at one point, they tell you to cut along the dotted line in the gasket, but if you do, you risk the chance of damaging the gasket if not cut correctly. Anyways, repeat the procedure above to replace and whalaa, done...
