3. If the engine temperature is cold (gauge on 'C') the coolant level must be at the top of the 'COLD FILL RANGE'. (Figure 2)

^ If necessary, top up the cooling system to the correct level with coolant.

4. If the engine temperature is normal (gauge on 'Normal') the level must be 30 mm (1.2 min) above the top of the 'COLD FILL RANGE'.

(Figure 2)

^ If necessary, top up the cooling system to the correct level with coolant.

BLEEDING THE COOLING SYSTEM / VERIFY COOLANT LEVEL
