Additional Notes

  • The Dodge Challenger with the 318ci engine carries a coolant capacity range of 15.1 to 16.5 liters, which is wider than a single fixed value. A range like this typically reflects variation between sub-configurations, such as differences in whether the heater circuit is included in the fill measurement.
  • The 360ci engine, available from 1973-1974, holds a fixed coolant capacity of 15.1 liters, representing the lower bound of the 318ci range rather than a higher figure despite the larger displacement.
  • Both the 318ci and 360ci configurations share a 12-month change interval under normal use conditions, meaning the coolant is specified for annual replacement regardless of mileage accumulated within that period.
  • The 318ci engine spans the full 1970-1974 model range, while the 360ci engine enters the specifications only from 1973-1974, reflecting a narrower production window for that displacement within the Challenger lineup.
