Maintenance and Specifications If the battery has been disconnected or a new battery has been installed, the clock and radio settings must be reset once the battery is reconnected. • Always dispose of automotive batteries in a responsible manner. Follow your local authorized standards for disposal. Call your local authorized recycling center to find out more about recycling automotive batteries. RE LE AD R TU N RECYCLE ENGINE COOLANT Checking engine coolant The concentration and level of engine coolant should be checked at the intervals listed in scheduled maintenance information. The coolant concentration should be maintained at 50/50 coolant and distilled water. For best results, coolant concentration should be tested with a refractometer such as Rotunda tool 300- ROB75240E available from your dealer. Ford does not recommend the use of hydrometers or coolant test strips for measuring coolant concentration. The level of coolant should be maintained at the FULL COLD level or within the COLD FILL RANGE in the coolant reservoir. If the level falls below, add coolant per the instructions in the Adding engine coolant section. Your vehicle was factory-filled with a 50/50 engine coolant and water concentration. If the concentration of coolant falls below 40% or above 60%, the engine parts could become damaged or not work properly. A 50/50 mixture of coolant and water provides the following: • Improved freeze protection. • Improved boiling protection. • Protection against rust and other forms of corrosion. • Proper function of calibrated gauges. 268 2011 Econoline (eco) Owners Guide, 3rd Printing USA (fus)
