Additional Notes

  • The Chrysler 300C LX (EU) cooling system capacities vary notably by engine type, ranging from 9.5–10.5 liters for the 3.6 V6 up to 13.9–14.3 liters for the 5.7 HEMI V8, reflecting the larger thermal mass and more extensive coolant passages associated with a larger displacement engine.
  • The 3.0 V6 CRD diesel engine carries a 12-liter cooling system capacity, which sits between the petrol V6 and V8 figures. Diesel engines typically run higher coolant volumes relative to displacement due to the additional heat management demands of compression ignition combustion.
  • The 3.6 V6 and 5.7 HEMI V8 both specify a capacity range rather than a fixed value — 9.5–10.5 liters and 13.9–14.3 liters respectively. A stated range in cooling system capacity typically accounts for variables such as residual fluid in the system during a drain-and-refill service versus a full system flush.
  • For the 3.0 V6 CRD covering the 2011-2012 period, the change interval is set at 160,000 km or 96 months (8 years) under normal use conditions. The 2012-2014 specification for the same engine retains the 160,000 km distance interval but extends the time-based limit significantly to 192 months, which equals 16 years.
  • The doubling of the time-based interval for the 3.0 V6 CRD from 96 months to 192 months between the two specification periods indicates a change in the coolant type or formulation standard applied to the later build range, as extended-life coolants are the primary basis for such long calendar-based service intervals.
  • The 3.6 V6 petrol engine maintains a consistent change interval of 168,000 km or 60 months across both the 2011-2012 and 2012-2014 specification periods, with no revision to either the distance or time-based limits between the two entries.
  • The 5.7 HEMI V8 shares the same 168,000 km and 60-month change interval as the 3.6 V6 across both specification periods, despite having a substantially larger cooling system capacity of 13.9–14.3 liters compared to the V6's 9.5–10.5 liters.
  • A 60-month (5-year) time-based coolant change interval, as specified for both the 3.6 V6 and 5.7 HEMI V8, is characteristic of Organic Acid Technology (OAT) or Hybrid OAT coolants, which are commonly factory-filled in vehicles from this era and offer longer service life than conventional silicate-based formulations.
