Fill up the circuit through the expansion tank up to the max
level mark. Secure a rubber hose to the bleed joint on the
head and insert it inside the expansion tank filler hole. Loo-
sen the joint and, if necessary, top-up with fresh coolant.
Start up the engine and wait until only coolant exits the hose,
hence tighten the joint on the cylinder head. Shut the engine
down, top-up with coolant and hence replace the expansion
tank filler cap. Warm the engine up to its operational tempe-
rature so to eliminate any air bubble within the main circuit.
Shut the engine off, let it cool down and hence check the
coolant level in the expansion tank reaches the max mark;
top-up as necessary.
