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: G13 OAT.
  • 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

  1. Check the level in the expansion tank on a cold engine — it should be between MIN and MAX marks.
  2. Fresh G13 OAT coolant is pink-violet. Brown, cloudy or sediment-filled coolant must be replaced immediately.
  3. Hydrometer test: density at 50/50 mix should be 1.060–1.080 g/cm³.
