Bleeding cooling system
General
If some or all of the coolant has been drained, the
cooling system must be bled after refilling.
Fill
Unscrew the cooling system cap and fill the cooling
system up to the "MAX" mark in the expansion reser-
voir.
Bleeding
Unfasten the clamp, pull off the coolant hose and wait
until coolant emerges from the coolant hose and the
cylinder head. Then reconnect the coolant hose and
fasten it with the clamp.
Top up the expansion reservoir to the "MAX" mark
again and screw on the cooling system cap.
Warm up the engine until the thermostat opens. Switch
off the engine and check the coolant level in the
expansion reservoir.
