You only need to bleed it if your running R-12. If you're running R-134, and the compressor cycles when you turn on the ac then usually you can just add a lb of R-134. Dont add too much though because too much will restrict the ac too. I generally use an old fridge compressor to purge and pump down the system, then add the recommended ammount of 134. This should be listed on a tag on the fan/radiator cover (in the front of the van) Hope this helps.
