    Mystery plug/connector near oil pan. Please help identify?

    Failed idler / drive pulley & belt. Alternator to blame?

    I was driving at 45 mph in traffic the other day and heard a horrid squeaking noise. Being on a road with no shoulders and heavy traffic, I had to continue on and wait for a safe spot to pull over. The sound was a VERY loud squeaking and it mysteriously went away. Of course, the battery light...
