Placing System In Operation

After component replacement and/or system servicing has been completed and all connections have been made, proceed as follows:

1. Evacuate the system using a vacuum pump.
2. Charge the system with new R-12 (refrigerant) according to each individual vehicle as outlined in the GENERAL COOLING SYSTEM article under GENERAL INFORMATION. Also see Refrigerant Capacity in this Section.
3. Leak test the system, with particular attention to all new connections and components.
4. Make a performance test of the system. Never assume that a recharging has automatically corrected a problem.
