The system must be filled properly to prevent
air locks. During filling, air must be vented
from the engine coolant passages. Be sure to
open the petcock on the aftercooler for
aftercooled engines.
The system has a design fill rate of 19 liters per minute
[5 U.S. gallons per minute]. Do not exceed this fill rate.
Wait 2 to 3 minutes to allow air to be vented. Then add
coolant to bring the level to the top.
