ENGINE COOLANT
Inspection
WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator. Wrap a thick cloth around the radiator cap. Slowly turn it a quarter of a turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.
CHECKING COOLING SYSTEM HOSES
Check hoses for the following:
- Improper attachment
- Leaks
- Cracks
- Damage
- Loose connections
- Chafing
- Deterioration
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:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator. Wrap a thick cloth around the radiator cap. Slowly turn it a quarter of a turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.
- To check for leakage, apply pressure to the cooling system at the reservoir filler neck using suitable tool and Tool.
Tool number: (J-33984-A)
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: (J-33984-A)
Standard : 110 kPa (1.12 kg/cm2, 16 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 deposits of waxy residue or other foreign material are on the black rubber gasket or the metal retainer.
