TVR Grantura

Coolant capacity & service interval

TVR Grantura coolant capacity ranges from 5.7 to 9 liters depending on the configuration. The data covers 6 different configurations.

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

Additional Notes

  • The TVR Grantura cooling system capacity holds at 9 liters across the MK.I, MK.II, MK.IIa, MK.III, and MK.III 1800 variants, spanning the 1958-1965 production period. A consistent figure across five distinct marks points to a shared cooling circuit architecture throughout most of the Grantura's lifespan.
  • The Grantura MK.IV 1800S (1966-1967) carries a notably lower cooling system capacity of 5.7 liters, a reduction of more than 3 liters compared to all earlier marks. A smaller coolant volume of this kind typically reflects a redesigned or downsized cooling circuit rather than a simple engine displacement change.
  • All six configurations list normal as the use condition for coolant capacity. In fluid specification tables, a normal use condition refers to standard operating environments, as opposed to severe duty cycles involving sustained high loads, extreme temperatures, or frequent short trips.
  • The 9-liter figure recorded for the MK.III 1800 (1963-1965) matches the capacity of the earlier MK.III (1962-1963) exactly, despite the 1800 designation indicating a different engine variant. Equal coolant volumes between the two suggest the cooling circuit dimensions were retained when the 1800 engine was introduced.
  • Coolant capacity figures in service specifications represent the total volume of the cooling system, including the engine block, cylinder head passages, radiator, and hoses. A 9-liter system is a moderately sized circuit for a small sports car of the 1958-1965 era.
  • The MK.IIa (1961-1962) sits chronologically between the MK.II and MK.III and shares the same 9-liter cooling system capacity as both surrounding marks. The "a" suffix in the designation typically denotes a minor revision rather than a full generational change, which aligns with the unchanged fluid specification.
