The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
Sonett V4 (1967-1969)
  • Use: Normal
  • Capacity 7,5 liter
Sonett II (1966-1967)
  • Use: Normal
  • Capacity 6,5 liter

Additional Notes

  • The Saab Sonett II, covering 1966-1967, has a cooling system capacity of 6.5 liters under normal use conditions.
  • The Sonett V4, spanning 1967-1969, carries a larger cooling system capacity of 7.5 liters under normal use conditions, reflecting the greater thermal demands of the Ford-sourced V4 engine compared to the two-stroke unit in the earlier Sonett II.
  • Between the two configurations, the V4 variant requires one full liter more coolant than the Sonett II, a difference that would be relevant when performing a complete cooling system drain and refill.
