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.
