ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
mileage (kilometer) intervals listed in thescheduled 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 (such as the Rotunda Battery and Antifreeze Tester,
014–R1060). The level of coolant should be maintained at 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.
•Enables calibrated gauges to work properly.
