Renault LS

Coolant capacity & service interval

Renault LS uses coolant with a capacity range of 11,2 to 13,5 liters. Service intervals consist of 600 hours or 12 months. The data covers 6 configurations.

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

Additional Notes

  • The Renault LS cooling system capacities across the 1986-1989 range fall into two distinct groups: 11.2 liters for the 65-series models and 13.5 liters for the 75-series and 85-series models. The larger capacity in the higher-numbered series reflects the greater engine displacement and thermal load those powerplants generate.
  • A cooling system capacity of 11.2 liters, as specified for the 65-12 LS and 65-14 LS, represents the total volume of coolant the system holds under a service fill condition, meaning the amount required when draining and refilling during routine maintenance rather than a full overhaul strip-down.
  • The 13.5-liter capacity shared by the 75-12 LS, 75-14 LS, 85-12 LS, and 85-14 LS indicates a noticeably larger cooling circuit, consistent with engines producing higher horsepower outputs and requiring greater heat dissipation capacity.
  • The 65-12 LS and 65-14 LS carry a coolant change interval of 600 hours under normal use conditions, with no calendar-based interval specified alongside. An hours-only interval is common in agricultural and industrial machinery, where seasonal or annual usage patterns make time-based intervals less practical than operational hour tracking.
  • The 75-series and 85-series models specify a dual coolant change interval of 600 hours or 12 months under normal use conditions, whichever comes first. The addition of a 12-month calendar limit means the coolant is replaced at least annually regardless of how many hours the machine has accumulated, accounting for coolant degradation over time even during low-use periods.
  • The -12 and -14 suffix designations within each series, such as 75-12 LS versus 75-14 LS, do not produce any difference in cooling system capacity or change interval. Both variants within the 75-series and both within the 85-series share identical 13.5-liter capacities and 600-hour/12-month service schedules.
  • All six configurations carry a normal use condition designation, meaning the specified intervals apply to standard operating environments. No separate severe-use intervals are listed for any of the 1986-1989 Renault LS cooling system entries.
