The fan belt cannot be tightened. The scenic has a tention pulley that automatically adjusts the belt. If the belt is slack, it is either the wrong size or it is stretched and needs to be replaced immediately as serious damage can occur in the event that the belt should slip off.

Not unless it is worn out.

The 3.0L V6 has a timing belt that must be replaced every 90,000 miles.
It is likely that the timing belt is not installed correctly. It is out of time.
I paid £360, although I got a few quotes around £500.
yes it does.
Very high probability of valve damage. Havent seen one yet that hasn't bent valves when belt broke. hope this helps
