Additional Notes

  • The dry fill capacity for the Acura TSX, CL9 2.4 in the 2004-2005 model years sits between 7.1 and 7.2 liters, representing the total volume required when filling a fully drained or rebuilt cooling system from empty.
  • The service fill capacity for the 2004-2005 2.4 is notably lower at 5.0-5.1 liters, reflecting the residual coolant that remains in the engine block and heater core during a standard drain-and-refill service.
  • For the 2006-2008 2.4, the dry fill capacity increases slightly to a range of 7.3-7.7 liters, while the service fill rises to 5.4-5.5 liters, indicating a modest expansion in cooling system volume compared to the earlier model years.
  • The 2004-2005 Canadian and USA market specifications share identical capacity figures and service intervals, with both markets listing a normal-use coolant change interval of 96,000 km or 60 months.
  • Under the first change only condition, the 2004-2005 USA market TSX 2.4 carries an extended interval of 192,000 km or 120 months, which applies specifically to the initial factory-fill coolant before transitioning to the standard normal-use schedule.
  • The same first change only interval of 192,000 km or 120 months applies equally to the 2004-2005 Canadian market specification, with capacity figures remaining consistent at 7.1-7.2 liters dry and 5.0-5.1 liters service fill.
  • No change interval is listed in the specifications for the 2006-2008 2.4 configuration, whereas the 2004-2005 entries carry explicit km and month-based intervals for both normal and first change only conditions.
