SYSTEM TESTING
|
RADIATOR CAP |
Make sure the engine is cool, remove the radiator cap.
Test the coolant specific gravity using a hydrometer.
STANDARD COOLANT CONCENTRATION: 1 : 1

Look for contamination and replace the coolant if necessary.
RADIATOR CAP/SYSTEM PRESSURE INSPECTION

|
RADIATOR CAP TESTER |
Remove the radiator cap.
Wet, he sealing Install the radiator cap on the tester. surface with water. pressure test the radjator cap
Replace the radiator cap if it does not hold pressure, or if the relief pressure is too high or too low.
It must hold the specified pressure for at least 6 seconds.
RADIATOR CAP RELIEF PRESSURE:
|
|
|
RADIATOR CAP TESTER |
108 - 137 kPa (1.1 - 1.4 kgf/cm2,16 - 20 psi)
Pressure test the radiator, engine and hoses, and check for leaks.
Excessive pressure can damage the cooling system components. Do not exceed 137 kPa (1.4 kgf/cm2, 20 psi).
Repair or replace components if the system will not hold the specified pressure for at least 6 seconds.
After checking the pressure, install the radiator cap securely.

• If any coolant gets in your eyes, rinse them with water and consult a doctor immediately.
|
RECOMMENDED ANTIFREEZE |
• If any coolant in swallowed, induce vomiting, gargle and consult a physician immediately.
• If any coolant gets on your skin or clothes, rinse thoroughly with plenty of water.

• The effectiveness of coolant decreases with the accumulation of rust or if there is a change in the mixing proportion during usage. Therefore, for best performance, change the coolant regularly as specified in the maintenance schedule.
• Mix only distilled, low mineral water with the antifreeze.
