Summary Verdict

The 2002 Ford F650, while built for heavy-duty service, exhibits some common reliability concerns typical of commercial vehicles of its era. The Caterpillar and Cummins diesel engines, while generally robust, can experience issues with fuel systems, turbochargers, and cooling components. Automatic transmissions, particularly the Allison series, may require attention to torque converters and fluid leaks. Suspension components like leaf springs and air bags are susceptible to wear and damage under heavy loads. Electrical systems can suffer from alternator failures and wiring corrosion. Owners should be vigilant for signs of frame rust and interior component failures like HVAC blowers and dashboard gauges. Regular maintenance and prompt attention to reported issues are crucial for maintaining the operational integrity of the F650.
