NOTE: Do not top up with water only. Water by itself reduces the rust-protective and anti-freeze qualities of the coolant and has a lower boiling point. It can also cause damage to the cooling system if it should freeze.
WARNING: If the engine is warm and you are going to top up coolant, unscrew the cap slowly in order to allow any excess pressure to escape.
CAUTION: The cooling system must always be kept filled to correct level. If it is not kept filled, there can be high local temperatures in the engine which could result in damage. Different types of anti-freeze/coolant may
