Alternator/Water Pump Belt Problems

[Jordanbutter]

Well I'm out of ideas (kinda). I had a shop replace the timing belt since then I've shreaded the Alt/Pump belt that was on there, snapped the brand new on I put on there 2 mins later, and now the third one is about to go out. The first one squeeked and then when I got up to speed stopped, the second one just squeaked from the get go, and this last one squeaked for a few seconds durning start up and then stopped. Until now cause it squeaks all the time. I noticed its very lose even though its new. The alternator was pulled as tight as possible so that shouldn't be out of adjustment. The water pump was checked when they did the timing belt and is good. Could the alternator be going out? I noticed that the battery (which is only a few months old) is only charging at low 13 volts when driving and high 12s when idleing, is that low? Any suggestions will help. Thanks?

1. Check if your harmonic balancer is separating.
2. Check if they put the water pump pulley on backwards (it will have a slight offset so the alt & PS belts don't quite line up with it.
3. Alt should be in 14's (14.4 is target). Even idling should be high 13's to 14's unless very heavy load.

I agree with the water pump pulley idea. My cousin put his on backwards and it threw the belt off after about 10 minutes.
