Santa Fe GLS V6-2.7L (2002)
Coolant: Description and Operation
ANTIFREEZE
The engine cooling system is provided with a mixture of 50% ethylene glycol anti-freeze and 50% water (For the vehicles of tropical area, the engine
cooling system is provided with a mixture of 40% ethylene glycol antifreeze and 60% water at the time of manufacture.)
Since the cylinder head and water pump body are made of aluminum alloy casting, be sure to use a 30 to 60% ethylene glycol antifreeze coolant to assure
corrosion protection and freezing prevention.
CAUTION: If the concentration of the antifreeze is below 30%, the anticorrosion property will be adversely affected. In addition, if the concentration is
above 60%, both the antifreeze and engine cooling properties will decrease, adversely affecting the engine. For these reasons, be sure to maintain the
concentration level within the specified range.
