ENGINE COOLANT


Inspection


LEVEL CHECK





- Check if the engine coolant reservoir tank level is within MIN to
MAX level when engine is cool.
- Adjust engine coolant level as necessary.

CHECKING COOLING SYSTEM FOR LEAKS

WARNING:
Never remove the radiator or reservoir cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator or reservoir.





- To check for leakage, apply pressure to the cooling system at the reservoir filler neck using suitable tool and Tool.

Tool number : EG17650301 (J-33984-A)

Leakage test pressure : 137 kPa (1.4 kg/cm, 20 psi)


CAUTION:
Higher pressure than specified may cause radiator damage.

NOTE:
In case that engine coolant decreases, replenish cooling system with engine coolant.
- If any concerns are found, repair or replace damaged parts.

CHECKING RESERVOIR CAP





- Check reservoir cap relief pressure using suitable tool and Tool.

Tool number : EG17650301 (J-33984-A)

Standard : 95 - 125 kPa (0.97 - 1.28 kg/cm2, 14 - 18 psi)


NOTE:
Apply engine coolant to the cap seal.
- Replace the reservoir cap if there is any damage in the negative-pressure valve, or if the open-valve pressure is outside of the limit.

CHECKING RADIATOR CAP





Inspect the radiator cap.

NOTE:
Thoroughly wipe out the radiator filler neck to remove any waxy residue or foreign material.
- Replace the cap if the metal plunger cannot be seen around the edge of the black rubber gasket.
- Replace the cap if deposits of waxy residue or other foreign material are on the black rubber gasket or the metal retainer.





- Pull negative-pressure valve to open it and make sure that it closes completely when released.
- Make sure that there is no dirt or damage on the valve seat of radiator cap negative-pressure valve.
- Make sure that there are no unusualness in the opening and closing conditions of negative-pressure valve.
