Suzuki RG(V)

Coolant capacity & service interval

Suzuki RG(V) coolant capacity ranges from 1,5 to 2,3 liters. Service intervals require a change every 24 months. The data covers 3 configurations.

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

Additional Notes

  • The Suzuki RG(V) coolant system capacities vary across the three configurations covered, ranging from 1.5 liters on the RG 250 up to 2.3 liters on the RG 500, reflecting the larger displacement and more extensive cooling circuit of the 500cc model.
  • The RG 500 (1980-1989) carries a cooling system capacity of 2.3 liters, the highest among the three variants listed, which corresponds to the greater thermal load generated by a 500cc racing-derived engine.
  • The RG 250 (1983-1990) has a cooling system capacity of 1.5 liters, while the RGV 250 (1990-1993) holds 1.6 liters despite sharing the same displacement class, indicating a slight difference in circuit volume between the two 250cc generations.
  • All three configurations share an identical coolant change interval of 24 months under normal use conditions, meaning the replacement schedule is consistent regardless of engine size or model generation.
  • The 24-month change interval applies specifically to normal use across the RG 250, RG 500, and RGV 250, and no alternative interval is specified for any other use condition in the available data.
  • The RGV 250 (1990-1993) represents the most recent generation in the lineup and carries a 1.6-liter cooling system capacity, a modest increase over the 1.5-liter figure associated with the earlier RG 250 (1983-1990).
