ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
mileage intervals listed in the scheduled maintenance guide. The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -36° C (-34° F). 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 full” of “cold fill range” level 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:
•
Freeze protection down to -36° C (-34° F).
•
Boiling protection up to 129° C (265° F).
•
Protection against rust and other forms of corrosion.
•
Enables calibrated gauges to work properly.
