thats a very simple thing to do but .....if was you ill pay for the job doneHow to change an alternator belt on a 1990 Mazda Protege?Never looked at one of these.. but there should be belt tensioner that you release with a breaker bar, slip the old belt off and new one on....
I would suggest the purchase of a Haynes repair manual for this car.. not too expensive.. at the auto parts store.. will show you how to do this kind of stuff.....
