Hi Guys
New to the forum and hoping to get some advice.

Recently picked up a 54 plate mk2 focus 1.6 TI-VCT with 65k on the clock.

Looking through the service record there is no sign of the cam belt being changed so I'm looking to get it done
In addition to this the thermostat is stuck open so I will get this done at the same time.

Got a quote for a local (oxfordshire) independant which came out as.
New cam belt
New water pump
New thermostat
New AUX belt
Fitted for 290+ VAT

Sounds reasonable but do I really need to change the water pump and AUX belt?

I know AUX belt is stretched to fit but the Haynes manual does not say you have to fit a new one each time.

Also the water pump is behind the cam belt so if that went after I would end up paying this all over again.
But what are the chances?
Do they fail often?
Maybe just a quick inspection to see its all ok?

A lot of questions I know but could really do with some advice.
Thanks
