Volvo semi truck d13 vnl a/c compressor info and take apart 20721587 

Volvo truck air compressor take apart, also mention a few common problems,
like if no no leak can be found but you know there is a leak for sure its very likely coming from the from of the compressor behind the clutch,
also try and stay away from refilling your a/c system with cans, because cans have oil with the Freon after a while the system ends up with more oil then it needs and to fix that need to drain flush and restart
