If you don't get a better response all I can suggest is looking at the theory of operation and system operation and repain instructions in a workshop manual. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online
After repairs are complete it is best to evacuate the system and see it maintains a vacuum (no more leak), then recharge the system using pressure gauges to check high and low side pressures.
