Can anyone serve up a possible reason for the alternator belt constantly becoming loose. I am getting squeeking and they are the proper belts finally. Very frustrating! After only ten miles the horrible squeeking begins and sure enough when I turn it off the damn belt is loose again. My mechanics I have are good ones, and they are stumped. I am too! Anyone know how to get this alternator belt to stay tight! I know it gets adjusted at the alternator but how do we keep it tight?? Thanks
