Navistar International®

Cold Advance Solenoid is an electrically operated valve that is used in diesel engines to control the fuel flow during cold starts. It is also known as a fuel shut-off solenoid or fuel cut-off solenoid. The solenoid is controlled by the engine's electronic control module (ECM) and is responsible for regulating the fuel flow to the engine during cold starts. The solenoid is typically located on the fuel injection pump and is activated by the ECM when the engine is started. The solenoid is designed to prevent excess fuel from entering the engine during cold starts, which can cause damage to the engine.
