The block heater for a 2003 Dodge Sprinter is located on the passenger side of the engine block, near the bottom. It is a cylindrical-shaped device with two wires coming out of it. The block heater is used to warm the engine block before starting the engine in cold weather. This can help to reduce engine wear and tear and make it easier to start the engine.
To use the block heater, simply plug the cord into a 120V outlet and turn on the switch. The block heater will automatically turn off when the engine reaches operating temperature.
