I have a 2000 Elantra that had the timing belt changed(it broke). It
seems to run fine and has plenty of power, but we're getting a belt
whine and screech when it's cold. The repair shop had reefed on the
belts(alternator and a/c compressor?) so they were very tight, so I
loosened them slightly to see if that was the problem. It didn't help.
I was looking at it, and it looks like the two driven pulleys may be
slightly out of line with the crank pulley. Could this be my
imagination, or is there a way to put the crank pulley on so that it's
not properly aligned.
