Hi Peter
The following thread from the forum also recommends to change also the Water pump along with cam belt. Also all axillary belts (i assume they are the other belts which you have mentioned) and all tensioners and bearings

A post from the thread
"I can't say categorically, but as you'd have to remove the belt to change the water pump, so it might be a good idea. On the coupe, many cambelt failures aren't due to the cambelt snapping, but the
auxillary belt snapping, then getting caught in the cambelt. A seized water pump can cause the aux belt to snap, so while it would cost more money to have it all done at once, it's less than changing them individually, and less than fixing a broken engine!"
"You should get the cambelt, the
auxillary belt, and all
associated tensioners done at the same time. It's not a bad idea to get the water pump changed too, as it's about £35 I think, and easy to do at the same time. This changes thae parts bill from about £15 (for the cambelt) to about £200 (tensioners are expensive!). But it's the labour that costs a bit anyway.
While the belt is being done, get the garage to check that the cambelt cover doesn't foul the cambelt, as on early cars the cambelt cover warps over time and can gently rub the cambelt."
please see this as sensible advice.i have seen 16 v's and 20 v's cambelts snap way before 50k.sometimes its the
counter rotating belt that snaps and takes the
cam belt with it.so
cam belts should be changed as follow.all non
turbo engines - 36k. all
turbo engines - 24k.the last figure is low,but these engines have the most wear on the
cam belt due to the torque.all tensioners and the water pump should be changed as well as any
auxillary belts.how much does a head cost to fix if the belt snaps?
Sorry to **** you off with so much reading on a holiday. But please try to clairfy my doubts on the auxiliary belt, counter rotating belt and the water pump
