Belts

[Hullkr88]

Hi

I have a Daimler double six 6l v12. 

This week I could hear a belt squeal noise which went away after revs. 

I started her up this morning in the cold and a noise had started when I steer. After 5 seconds a smoke comes out. 

Iv looked at the belts and the small thin belt which goes over the fan stops and starts. I don’t know where to start. Could this be a belt problem or is something stopping the belts rotation. The noise is pretty bad from the steering. 

Thanks for looking.
