Maintenance and Specifications 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 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. • Enables calibrated gauges to work properly. When the engine is cold, check the level of the engine coolant in the reservoir. The engine coolant should be within the COLD FILL RANGE as listed on the engine coolant reservoir. Refer to scheduled maintenance information for service interval schedules. If the engine coolant has not been checked at the recommended interval, the engine coolant reservoir may become low or empty. If the reservoir is low or empty, add engine coolant to the reservoir. Refer to Adding engine coolant in this chapter. 375 2012 Explorer (exp) Owners Guide, 2nd Printing USA (fus)
