Filling and bleeding
There is no heater matrix water control valve.
Water flow is continuous in the heater matrix, which
contributes to the cooling of the engine.
FILLING
It is essential to open the bleed screw on the
cylinder head coolant pipe housing outlet.
Fill the circuit through the expansion bottle opening.
Close the bleed screw as soon as the fluid runs out in
a continuous jet.
Start the engine (2500 rpm).
Adjust the level by overflow for a period of about
4 minutes.
Tighten the expansion bottle cap.
BLEEDING
Let the engine run for 20 minutes at 2500 rpm, until
the engine cooling fan operates (time required for
automatic degassing).
Check the liquid level is at the "Maximum" marker.
DO NOT OPEN THE BLEED SCREW(S) WITH THE
ENGINE RUNNING.
REFIT THE EXPANSION BOTTLE CAP WHILE THE
