Truck? Replacing everything in the system. Has a reman compressor but it really doesnt give specifics except that it has a minimal amount of oil in it.

Also am wondering what the best way to flush the system out myself would be?

The system is a 134A system with a R4 compressor.

Thanks
 
Your system has to be evacuted and the flushed with a special solution to remove all the 134a. then it has to be charged and at that the the certified mechanic will put the right ac oil in it. also be sure you change the orfice it a small inside filter in the ac lines. the reason for evacution is to see if it holds pressure and theres no leaks in the system before it is charged.
