Antifreeze

Check the cooling system for damaged hoses, loose or leaking connections, or other possible causes of coolant leaks.




ANTI FREEZE

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 anti-freeze 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.




MEASURING OF ANTIFREEZE CONCENTRATION

Run the engine until the coolant is fully mixed. Drain some coolant (antifreeze), and then measure the temperature and specific gravity of the coolant. Determine it's concentration and safe working temperature. If the coolant is short of antifreeze, add antifreeze to a concentration of 50%. (Tropical Areas: 40%)
