Mine's looking a bit shabby (been looking that way for a good old while TBH) so I decided to change it. AFAI can see on WIS they recommend taking the fan off & the shroud out. The problem is someone has had a go at the bolt holding the fan on & I can't get anything to work to take it our, can't even tell if it's a star or hexagonal such is the state of it (which is it?). Question is, can I fit the belt leaving the fan & shroud in place or do I just drive it until the belt goes & worry about it then? TIA.
