Rover P5

Coolant capacity & service interval

The Rover P5 coolant specifications cover a capacity range of 9 to 14.7 liters. Four configurations of the model are included in the data.

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

TypeSpecifications
3.5-Litre (1967-1973)
  • Use: Normal
  • Capacity 9 liter
3-Litre MK III (1965-1967)
  • Use: Normal
  • Capacity 14,7 liter
3-Litre MK II (1962-1965)
  • Use: Normal
  • Capacity 13 liter
3-Litre MK I (1959-1962)
  • Use: Normal
  • Capacity 13 liter

Additional Notes

  • The Rover P5 3-Litre MK I and MK II share an identical cooling system capacity of 13 liters across their respective production spans of 1959-1962 and 1962-1965.
  • The 3-Litre MK III, produced from 1965-1967, carries a notably higher cooling system capacity of 14.7 liters compared to the earlier MK I and MK II variants at 13 liters.
  • A cooling system capacity of 14.7 liters is among the larger figures for a six-cylinder engine of the era, suggesting an expanded coolant jacket or additional circuit volume within the MK III engine bay layout.
  • The Rover P5 3.5-Litre, introduced in 1967, has a substantially reduced cooling system capacity of 9 liters, a figure considerably lower than all three preceding 3-Litre variants.
  • The reduction from 14.7 liters in the 3-Litre MK III to 9 liters in the 3.5-Litre reflects the architectural difference between the inline six-cylinder and the Buick-derived aluminum V8 engine, the latter being known for its comparatively compact and lightweight cooling requirements.
  • All four configurations carry a normal use condition designation, meaning the stated capacities apply to standard operating environments without a separate severe-duty interval or fill specification listed.
