CHECKING AND CHANGING THE EN- GINE COOLANT
WARNING: Do not remove the radiator cap when the
engine is hot. When the engine is hot, the engine coolant is under pressure and mayerupt through the opening if the cap isremoved. You could be seriously burned ifyou do not observe this precaution. Do notremove the radiator cap until the radiator iscool to the touch. G050B01A-AAT
Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant shouldbe compatible with aluminum engine parts.Additional corrosion inhibitors or additives shouldnot be used. The cooling system must be main-tained with the correct concentration and typeof engine coolant to prevent freezing and corro-sion. Never allow the concentration of anti-freeze to exceed the 60% level or go below the35% level, or damage to the cooling systemmay result. For proper concentration when add-ing or replacing the engine coolant, refer to thefollowing table.

To Check the Coolant Level The coolant level can be seen on the side of the plastic coolant reservoir. The level of the cool-ant should be between the "LOW" and "FULL"lines on the reservoir when the engine is cool.If the level is below the "LOW" mark, addengine coolant to bring it up between "LOW"and "FULL". If the level is low, inspect forcoolant leaks and recheck the fluid level fre-quently. If the level drops again, visit yourHyundai dealer for an inspection and diagnosisof the reason.
7. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-ter 9 for engine oil capacity.
8. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.

In addition, it is imperative that only
an approved grade and specificationof oil is used to avoid the possibility of serious engine damage and prema-ture wear. The use of "budget price" oil is a false economy that must be avoided if the maximum reliability anduseful life is to be obtained from the vehicle.
