hi ...
mmm, first ... forgive me for nosing in on your "hot-rod" forum with my blatently non-hot-rod (p.o.s) pontiac grand am ...

it's a 93 ... 3.3 v-6 pontiac grand am



i've replaced alternator and serpentine belt ...

after jump starting .. it sounded good ... but having been sitting a spell ... (the ports probably need to be cleaned ... ) anyhow .. when engine cuts out ... there is a "clunking" sound .. and seems to be the alternator , or in that vicinity ... i started it again .. same thing ....

when belt is "engaged" ... , meaning , with tension .. i can only spin alternator "fan" by hand ... approx 180 degrees and then it locks ... i can spin it back and forth ....to the same spot ... but with out tension on the belt can spin it freely , completely around, as well, the other pulleys ...i do have A/C ...

i'm positive the belt is "threaded correctly" ... i had my curious neighbor check it out ...
then i walked away for about an hour ... and went back to look again ....to double check ...

any ideas or words of wisdom ... much appreciated ...
