My service manual (alldatadiy) lists the torques as:

- Fan to Viscous coupling: 100 Nm
- Viscous coupling to pulley: 455 Nm

Those sound pretty high to me but the 45 Nm that is listed in the first post sound pretty low.

Can anyone clarify this one? I recall that I torqued mine to around 90 Nm when I changed it last year as that value 'felt' about right.
