Maintenance and care • Do not add extra inhibitors or additives to the coolant. These can be harmful and compromise the corrosion protection of the engine coolant. • Do not mix with recycled coolant unless from a Ford-approved recycling process (see Use of Recycled Engine Coolant section). If equipped with the 3.8L V6 engine, to avoid scalding hot steam or coolant from being released from the engine cooling system, never remove the radiator cap from the radiator while the engine is running or hot. Failure to follow this warning may result in damage to the engine's cooling system and possible severe personal injury. If equipped with the 4.6L V8 engine, to avoid scalding hot steam or coolant from being released from the engine cooling system, never remove the pressure relief cap from the engine coolant reservoir while the engine is running or hot. Failure to follow this warning may result in damage to the engine's cooling system and possible severe personal injury. If you must remove the pressure relief cap or radiator cap (depending upon engine application), follow these steps to avoid personal injury: 1. Before you remove the cap, turn the engine off and let it cool. 2. When the engine is cool, wrap a thick cloth around the cap. Slowly turn cap counterclockwise until pressure begins to release. 3. Step back while the pressure releases. 4. When you are sure that all the pressure has been released, use the cloth to turn it counterclockwise and remove the cap. 161
