Navistar A300

The register lists here 45 versions with 200 to 550 kW rated output at 1,600 to 2,600 rpm, with electronic direct injection and diesel as fuel. Maximum torque ranges from 540 to 1,850 Nm at speeds of 900 to 1,600 rpm.

The A range covered the heavy and medium-heavy truck segment of Navistar's International models and competed directly with Cummins, Detroit and PACCAR MX engines; the well-known series problems with the in-house exhaust-treatment approach in this era are among the reasons Navistar later abandoned its own engine programme and, as part of Traton today, again relies on outside engines.

On a used purchase from these model years, what matters especially is the service history of the exhaust aftertreatment and any modifications made, the condition of the injection system and turbocharger, the cooling system and charge-air cooler, and matching the engine-family code to the unit actually fitted; spares run through the International/Navistar dealer network.
