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.
