Engine damage when topping up with cold coolant if the engine is at operating temperature.
For this reason:
S Do not add cold coolant.
S Let the engine cool down.
NOTE
Engine damage due to lack of antifreeze and corrosion inhibitor
An incorrect mixture of antifreeze and corrosion inhibitor leads to failure of the cooling system.
