contributes to the cooling of the engine.

cylinder head coolant pipe housing outlet.
Fill the circuit through the expansion bottle opening.

a continuous jet.

Adjust the level by overflow for a period of about
4 minutes.

the engine cooling fan operates (time required for
automatic degassing).
Check the liquid level is at the "Maximum" marker.

ENGINE RUNNING.
