Mixing Rules
- Do not mix different coolant types (G11/G12/G13) — mixing causes a chemical reaction and sludge formation.
- When topping up, use the same type: G11.
- Always dilute concentrate with distilled water at a ratio of 50/50.
- Freeze protection at 50/50 mix: approximately –37°C.
Checking Coolant Level and Condition
- Check the level in the expansion tank on a cold engine — it should be between MIN and MAX marks.
- Fresh G11 coolant is green. Brown, cloudy or sediment-filled coolant must be replaced immediately.
- Hydrometer test: density at 50/50 mix should be 1.060–1.080 g/cm³.
