ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
intervals listed inscheduled maintenance information.The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -34°F (-36°C). Coolant concentration
testing is possible with a hydrometer or antifreeze tester. 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 theAdding engine coolantsection.
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:
•Freeze protection down to -34°F (-36°C).
•Boiling protection up to 265°F (129°C).
•Protection against rust and other forms of corrosion.
•Proper function of calibrated gauges.
