Cooling System
Coolant
Check (Level)
CAUTION The cooling system is pressurised when the coolant is hot. When you remove the cap, hot coolant
can spray out and burn you. Make sure that the engine is cool before you work on the cooling system.
1. Carefully loosen the radiator cap. Let any pressure escape before removing the cap.
2. Remove the radiator cap.
3. Check that the coolant level is flush with the top of the filler neck.
4. Fill with 50% antifreeze and 50% decalcified water until it reaches the correct level and replace the cap.
5. Top liquid up until the pipes inside the radiator are covered approximatively by the amount specified. Do
not overfill the radiator, but leave room for the coolant to expand.
Length/Dimension/Distance: 5mm
6. Run the engine to raise the coolant to working temperature and pressure. Stop the engine, checks for leaks
and re-check the fluid level.
