On the way to a weekend campout, the Westy started smoking thru the left rear engine vents. I pulled over and after making sure I didn't have an engine fire (yes I have new fuel lines), I cracked the lid and discovered that my new A/C Belt with less than 50 miles on it had been torn apart.  The belt shroud was loose and heat blistered on the inside, but the belt doesn't look like it was worn, just ripped apart.  

The A/C pulleys don't turn, but I don't know if they are suppose to.  

Question: Does it sound like a  new compressor, or was the belt installed incorrectly.

If a compressor change is in order, should it be OEM or what make do you recommend?

What are ball park $$ for parts and labor?

Thanks,
