Belts. Changing. Info please.

What time frequency / mileage. Should the belts be changed please ?



My car (TF 160) is my daily driver. I do about 300 miles / week normally.



The belts were replaced during a water pump fit carried out by MGOC about 3 years ago now.



Recently the alternator belt occasionally squeaks at start-off in the wet. So I'm going to change the belt to give piece of mind.



But I'm now thinking ..."what about the other belts" ?



Your thoughts please, thanks ........
