Additional Notes

  • The De Tomaso Longchamp carries a cooling system capacity of 18 liters across both the 1972-1973 and 1974-1979 configurations. An 18-liter figure is notably large for a passenger car, reflecting the demands of a high-displacement engine requiring substantial thermal management volume.
  • The check interval for the cooling system is set at 6,000 km for the 1972-1973 Longchamp under normal use conditions. At that interval, a technician would typically inspect coolant level, concentration, and condition rather than perform a full drain and refill.
  • The 1974-1979 Longchamp shares the same 6,000 km check interval under normal use conditions as the earlier production years, alongside the identical 18-liter capacity figure.
