Fill the circuit through the opening in the expan-
sion bottle.
Tighten the bleed screws as soon as the liquid
flows in a continuous jet.
Start the engine (2 500 rpm).
Adjust the level by overflow for a period of about
4 minutes .
Close the bottle.
BLEEDING
Allow the engine to run for about 10 minutes at
2 500 rpm, until the fan(s) operate (time necessary
for automatic degassing).
Check the liquid level is at the "Maximum" mar-
ker.
