COOLANT INSPECTION
● Radiator coolant mixes the distilled water.
•Coolant mixes the distilled water and radiator
coolant base solution with about 5°C of tolerance in
respect to the minimum temperature.
•Radiator coolant is toxic. Keep it away from skin, eyes
and clothes.
- If any coolant gets on your skin or clothes, rinse
thoroughly with soap and water.
- If any coolant gets in your eyes, rinse them with water
and consults a doctor immediately.
- If any coolant is swallowed, induce vomiting, gargle
and consult a physician immediately.
- Especially pay attention to reserve the coolant. Keep
out of reach of children.

COOLING SYSTEM INSPECTION

COOLANT GRAVITY TEST
•Follow the hydrometer manufacturer's instructions.
● Check the coolant gravity using a hydrometer.
● Look for contamination of the coolant.
