Driving Your vehicle is also equipped with a bypass relief valve, located on the fuel control module, which provides fuel flow to the engine if the fuel pickup should become plugged by ice or wax. To allow this bypass valve to function and avoid engine fuel starvation, it is recommended that, during cold weather operation 32°F (0°C) or below, the fuel level in your tank should not be allowed to drop below 1⁄4 full. This will help prevent air from entering the fuel system and stalling the engine. In cold weather below 32°F (0°C) your diesel engine will slowly increase to a higher idle speed if left idling in P (Park). As the engine warms-up, the engine sound level will decrease due to the activation of PCM-controlled sound reduction features. If your vehicle is operated in a heavy snow storm or blowing snow conditions, the engine air induction may become partially clogged with snow and/or ice. If this occurs, the engine may experience a significant reduction in power output. At the earliest opportunity, clear all the snow and/or ice away from the air induction inlet. Operation in snow Vehicle operation in heavy snowfall or in dry loose snow that may swirl around the front of the vehicle may feed excessive amounts of snow into the air intake system. This could plug the air cleaner with snow and cause the engine to stall and/or lose power. Refer to Air filter restriction gauge and Engine air filter in the Instrument Cluster chapter of this supplement for more information. Operation in standing water Ingestion of water into the diesel engine can result in immediate and severe damage to the engine. If driving through water, slow down to avoid splashing water into the intake. If the engine stalls, and ingestion of water into the engine is suspected, do not try to restart the engine. Consult your dealer for service immediately. Engine block heater (if equipped) Refer to the Driving chapter in the Owner's Guide. 14 2005 Econoline (eco) Supplement USA (fus)
