Summary Verdict

The 2000 Ford F650, particularly with its Caterpillar and Cummins diesel engine options, is generally a reliable work truck. However, common issues such as injector pump and turbocharger problems on the Caterpillar, and fuel injector issues on the Cummins, require attention. Transmission reliability is good, though torque converter issues in automatics and clutch wear in manuals are noted. Suspension leaf springs can break under heavy use. Electrical systems can suffer from corrosion, and alternators may fail. Exterior rust is a concern in certain environments. Interiorly, HVAC blower motors and seat mechanisms can wear out. Proactive maintenance and addressing these specific potential failures will contribute to the longevity and operational efficiency of the F650.
