I’ve been helping my little sister do maintenance on her 2000 Mazda Protoge. For some reason she did not have the brace that allows you to tension the alternator belt properly. I didn’t know what it looked like or all the parts necessary to piece it together. Luckily I found a parts diagram for a Mazda Protoge for years 1999, 2000, 2001, 2002, 2003.
When I went to the dealer the part numbers didn’t match, but it was still helpful.
