Daihatsu Rocky / Fourtrack

Coolant capacity & service interval

Daihatsu Rocky / Fourtrack coolant capacity ranges from 7,2 to 10,6 liters. Service intervals require changes every 40000 km or 48 months. The data covers 4 configurations.

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

Additional Notes

  • The Daihatsu Rocky / Fourtrack 2.0 petrol engine covering 1984-1994 carries a standard cooling system capacity of 7.2 liters, which represents the base fill without auxiliary climate equipment.
  • When the 2.0 is fitted with a 4-zone air conditioning system, the cooling system capacity rises to a range of 7.9-9.0 liters, reflecting the additional thermal load and circuit volume introduced by that configuration.
  • The 2.2 petrol variant from 1994-2003 holds 7.9 liters, a figure that aligns with the lower end of the 4-zone air conditioning range seen in the earlier 2.0, though the 2.2 specification carries no such conditional split.
  • The naturally aspirated Diesel variant across 1984-2003 has a base cooling system capacity of 9.8 liters, a notably higher figure than either petrol variant, consistent with the greater heat rejection demands of a diesel combustion cycle.
  • Adding a heater circuit to the Diesel raises the capacity to 10.6 liters, an increase of 0.8 liters that accounts for the additional coolant volume circulating through the heater core.
  • The Turbo Diesel across 1984-2003 holds 10.6 liters as its standard capacity, matching the heater-equipped naturally aspirated Diesel figure, which reflects the turbocharger's contribution to overall thermal load even without a separately noted heater addition.
  • All four configurations share an identical service interval of 40,000 km or 48 months under normal use conditions, meaning the change frequency is consistent regardless of engine type or capacity volume.
