Additional Notes

  • The Acura RSX DC5 cooling system carries a dry fill capacity of 6.4 liters across all configurations. Dry fill represents the total volume required when filling a completely drained or rebuilt system, such as after an engine overhaul or major cooling system repair where all passages, the heater core, and the reservoir are empty.
  • The service fill capacity is 5.1 liters across all RSX configurations. Service fill reflects the amount of coolant needed during a routine drain-and-refill, where residual fluid remains in the heater core, block passages, and other areas that do not fully drain during a standard service procedure.
  • The difference of 1.3 liters between the dry fill and service fill values indicates the volume of coolant that typically remains trapped in the system during a routine service drain, which is a normal characteristic of closed-loop cooling systems with integrated heater circuits.
  • Under normal use conditions, the coolant change interval for all RSX Base and Type-S configurations, in both USA and Canadian markets, is 96,000 km or 60 months, whichever comes first.
  • A separate first-change-only interval of 192,000 km or 120 months applies to all configurations. This extended interval is specific to the initial factory-fill coolant, which is formulated to last longer than subsequent refills before the first scheduled change.
  • The RSX Type-S is split into two distinct year ranges in the specifications: 2002-2004 and 2005-2006. Both ranges share identical capacity and interval values across both the USA and Canadian markets.
  • The RSX Base covers the full 2002-2006 span as a single configuration in both markets, while the Type-S is divided into two sub-ranges, reflecting a model year distinction that the specifications treat as separate entries despite identical coolant data.
  • Capacity and interval specifications are identical between the USA and Canadian market variants for every RSX configuration listed, meaning no regional differences exist in the cooling system service data across these specifications.
