How do you change a 2002 Mazda protege alternator belt?

First you need to remove the AC belt to be able to install the alternator belt.

This can be accomplished by loosening the hinge bolt and set bolt on the side. Then adjust the tensioner bolt till you can slip the AC belt off.

Then you need to loosen the alternator hinge bolt and the set bolt on the side. Then adjust the tensioner bolt to the point where you can put the new alternator belt on to the main drive pulley, water pump and alternator pulleys. Then tighten the tensioner bolt till the belt has about 1/2 of give in the middle of the belt. Once in place tighten the set belt and hinge bolt.

Repeat the same process for putting the AC belt back on.

*I have replaced my alternator belt 4 times in the last two years and need to install it for the 5th time. I just found out that there is a consistent issue with Protoges and aftermarket alternator belts and proper fit. Save your self the time of doing this job over and over again and buy the OEM belt from your Mazda dealer.*
