On a 2002 Chevy Express 2500, the temperature sensor, commonly known as the engine coolant temperature (ECT) sensor, is typically located near the thermostat housing on the engine block. It can usually be found on the driver's side of the engine, close to the intake manifold. To access it, you may need to remove some components, as it can be somewhat concealed. Always consult the vehicle's service manual for specific details and diagrams.
