  • Use: Normal
  • Capacity 18 liter
  • Change 50000 km/ 36 months

Additional Notes

  • The Bentley Turbo R/S/RT cooling system holds 18 liters of coolant, a capacity consistent with large-displacement luxury vehicles where extended coolant passages through the engine block, cylinder heads, and cabin heating circuits contribute to a high total system volume.
  • Under normal use conditions, the coolant change interval for the Turbo R/S/RT is set at 50,000 km or 36 months, whichever comes first, meaning time elapsed can trigger a service requirement even before the distance threshold is reached.
  • The 36-month time-based interval reflects the degradation behavior of coolant additives, particularly corrosion inhibitors and pH stabilizers, which break down over time regardless of mileage accumulated during the 1986-1999 model span.
