Additional Notes

  • The Mercury Monterey 4.2 V6 cooling system holds 14 liters as its standard capacity across the 2004-2007 model years.
  • When equipped with a 4-zone air conditioning system, the cooling system capacity increases to 15 liters, reflecting the additional thermal load placed on the circuit by the expanded climate control hardware.
  • Under normal use conditions, the coolant change interval is set at 80,000 km or 36 months, whichever comes first.
  • Under initial service conditions, the same 4.2 V6 cooling system carries an extended change interval of 150,000 km or 60 months, which is nearly double the normal use schedule in both distance and time.
  • The gap between the normal and initial service intervals suggests the first coolant fill uses a formulation rated for longer service life before the standard replacement cycle takes over at subsequent changes.
