To check the coolant level, ensure that the engine has been shut down for at least halfan hour. The coolant level can be checked visually and should be between the two level marksformed on the front of the white plastic expansion tank. If required, top up the level with coolant (50% clean tap water and 50% ethylene glycolbased anti-freeze) through the expansion tank filler cap. Do not use water only to top up as this weakens the coolant mix, reducing the level offrost protection and anti-corrosion protection of the coolant.
