Summary Verdict
The 2004 Chevrolet Express 2500 is a capable and durable van, particularly for commercial use. Its powertrain options, while generally reliable, can experience issues such as intake manifold gasket leaks across most engines and torque converter problems with the 4L60-E transmission. The 5.3L and 6.0L V8s are also susceptible to Active Fuel Management (AFM) lifter issues. Suspension components like ball joints and leaf springs are common wear items, especially under heavy use. Electrical gremlins, often related to the BCM or alternator, can also arise. Rust is a significant concern for older models, particularly in corrosive climates. Overall, with diligent maintenance and awareness of these common issues, the Express 2500 can remain a dependable vehicle.
