I recently just got done replacing my AC compressor and several other AC components in my 99 Honda Civic DX. When I got done putting the belts on and tightening them up I started the car. I immediately noticed smoke coming from the belt area. I turned off the car and loosened the belt. I started it back up and gave it another shot. It took a while, but eventually it started squealing and smoking again. What are some possible causes of this? I did have trouble loosening the idler pulley the first time and had to take the entire idler pulley bracket off and use a pair of vise grips to get the nut off. I replaced it with a new nut from Home Depot and put it all back together. Could the idler pulley be bad all of a sudden? Did not have this problem before I took the car apart.

Thanks,

Matt
