Renault RS

Coolant capacity & service interval

Renault RS coolant capacity ranges from 11,2 to 13,5 liters. Service intervals occur every 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 RS 61-12 and 61-14 cooling systems share an 11.2-liter capacity, the smallest figure across all six configurations listed. In agricultural and industrial machinery, cooling system capacity generally reflects engine displacement and thermal load, so the lower figure in the 61-series aligns with its smaller power rating relative to the 68 and 75 series.
  • The 68-12, 68-14, 75-12, and 75-14 RS models all carry a 13.5-liter cooling system capacity, representing a notable step up from the 61-series. A difference of 2.3 liters between the two capacity groups indicates a meaningfully larger cooling circuit, typically associated with higher-displacement engines requiring greater heat dissipation.
  • All six configurations share an identical service interval of 600 hours or 12 months under normal use conditions, whichever comes first. The dual-trigger format, combining an engine-hours threshold with a calendar limit, is standard practice for machinery that may accumulate operating hours unevenly across seasons.
  • The 61-series models carry a production range of 1985-1990, while the 68 and 75 series begin a year earlier in 1984, also running through 1990. This means the 68 and 75 configurations have one additional model year represented in the specifications.
  • Within each power class, the two-wheel-drive and four-wheel-drive variants (denoted by the -12 and -14 suffixes respectively) share identical cooling system capacities and service intervals. The drivetrain configuration does not appear to alter the cooling circuit volume or the recommended change schedule in any of the listed rows.
  • A 600-hour service interval is a relatively extended threshold for coolant replacement in tractor applications, reflecting the expectation of moderate annual workloads under normal operating conditions. Machines used in more demanding environments would typically require more frequent attention, though the specifications here apply strictly to normal use.
