Elantra GLS Wagon L4-2.0L (2000)
Coolant: Testing and Inspection
Check the cooling system for damaged hoses, loose or seeping connections, or other possible cause of coolant loss.
ANTIFREEZE
The engine cooling system is provided with a mixture of 50% ethylene glycol anti-freeze and 50% water at the time of manufacture.Since the cylinder
head and water pump body are made of aluminum alloy casting, be sure to use 30 to 60% ethylene glycol antifreeze coolant to provide corrosion
protection and freezing prevention.
NOTE: If the concentration of the antifreeze is below 30%, the anticorrosion property will be adversely affected. In addition, if the concentration above
60%, both the antifreezing and engine cooling properties will decrease, adversely affecting the engine. For these reasons, be sure to maintain the
concentration level within the specified range.
MEASUREMENT OF ANTIFREEZE CONCENTRATION
Run the engine until coolant is fully mixed. Drain some coolant (antifreeze), measure temperature and specific gravity of the coolant. Determine
concentration and safe working temperature. If the coolant is short of antifreeze, add antifreeze up to a concentration of 50%
COOLANT CHANGE
WARNING: Hot engine coolant can injure you.Never open the radiator cap when the engine is hot.Allow it to cool first.When removing the radiator
cap, take care to avoid contact with lot coolant or steam. place shop towel over the cap and turn the cap counterclockwise a little to let pressure escape
through the vinyl tube. After relieving the pressure, remove the cap by slowly turning it counterclockwise.
1. Remove the radiator cap, radiator drain plug and engine drain plug to drain coolant.
2. Remove the reserve tank and drain coolant.
3. After draining coolant completely, reinstall the drain plugs and flush the engine and radiator using a radiator cleaning fluid.
4. After the flushing is completed, completely drain the cleaning fluid and install the radiator and engine drain plug.
5. Select an appropriate concentration for safe operation temperature within the range of 30 to 60%. Refill the system with a high quality ethylene
glycol antifreeze at the selected concentration.A convenient mixture is 50% water and 50% antifreeze solution.[Freeing point: -36 °C (-32.8 °F)]
.Reinstall the radiator cap.
6. After running the engine a while,check the coolant level and add coolant until the specified coolant level is maintained.
7. Add coolant to the reserve tank between the "FULL" and "LOW" mark if necessary.
NOTE: Do not overfill the reserve tank.
