ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should
be checked at the mileage intervals in the
Scheduled Maintenance Guide. The coolant
concentration should be maintained at 50/50 coolant
and 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 gages to function properly
