I replaced the serpentine belts on my 2001 Honda accord EX 4 cylinder yesterday.
When test running, I can smell a bit burning rubber [both belts were rotating]. I thought It was just a burning smell from some dropped WD40 that I used to loosen the nuts.
However, today morning, I looked at the crank pulley and found some of the trace is yellow [see pic]. I am not sure if they were there before or is caused by burning. However, I do remember that when I was checking the old belts, they donot have yellow sign on it, so I guess the yellow trace are new.
In that case, what might be the issue? Such as belt too tight, too loose?
Urgency here is because this is my only car now. thanks for help.

 

Sorry, just saw your post.

Moved your post to the proper forum. The DIY section is more for write-ups.

Make sure the belt is centered on the crank pulley and not off a notch to one side. The belt tension could be too tight and you may need to loosen.
