Known issues on the 2001 Express 2500. The federal record shows a single recall for this year, covering replacement oil filters that can seal poorly and let engine oil out, with fire the consequence if it reaches hot metal. Owner complaints number two, one on the body structure and one on engine and engine cooling, neither enough to characterize a model year. Cooling system testing, thermostat and coolant specifications and radiator service are documented here, as are the body and frame procedures, so a van can be assessed on measurement rather than on reputation.
