MG MGA

Coolant capacity & service interval

MG MGA coolant specifications cover a capacity range of 5.7 to 7.7 liters. The data includes four different configurations. The fluid type specified is coolant for normal use.

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

TypeSpecifications
MGA 1600 (1959-1962)
  • Use: Normal
  • Capacity 5,7 liter
MGA 1600 Mk. II (1959-1962)
  • Use: Normal
  • Capacity 5,7 liter
MGA Twin Cam (1959-1962)
  • Use: Normal
  • Capacity 7,7 liter
MGA 1500 (1955-1959)
  • Use: Normal
  • Capacity 5,7 liter

Additional Notes

  • The MG MGA 1500 carries a cooling system capacity of 5.7 liters, a figure that applies to normal use conditions across its 1955-1959 production span.
  • Both the MGA 1600 and the MGA 1600 Mk. II share an identical 5.7-liter cooling system capacity under normal use conditions, matching the figure established by the earlier 1500 variant.
  • The MGA Twin Cam stands apart from the other configurations with a notably larger cooling system capacity of 7.7 liters, representing a 2-liter increase over the 5.7-liter figure seen across the pushrod-engined variants.
  • A 7.7-liter coolant capacity in a small British sports car of the late 1950s reflects the greater thermal demands of a twin-cam engine design, which generates more heat at the cylinder head than a conventional pushrod unit of similar displacement.
  • The 5.7-liter capacity shared across the MGA 1500, 1600, and 1600 Mk. II indicates a consistent cooling system architecture among the pushrod variants despite the displacement increase from 1500cc to 1600cc between model generations.
