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.
