Technical Service
SUBJECT
Proper Evacuation and/or Filling of Cooling System after Repairs
MODEL
All
SITUATION
It can no longer be assured that all air is bled from a modern cooling system after it has been opened for repairs. This can result in poor performance
of the cooling system and also erratic operation of systems utilizing cooling system temperature values. A special tool has been developed that
ensures complete evacuation of all air in the system prior to filling, and also validates if the system is free of leaks prior to filling with coolant.
PROCEDURE
The Coolant Vacuum Charger tool P/N 81 39 2 152 470 (SI B04 34 08) must be used after completing major cooling systems repairs, or when the
cooling system is drained and needs to be refilled with fresh coolant. Repair instructions for operating the vacuum charge unit are in the attachment
below.
