which equates to a freeze point of -34°F (-36°C). Coolant concentration
testing is possible with a hydrometer or antifreeze tester. The level of
coolant should be maintained at the FULL COLD level or within the
COLD FILL RANGE 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 -34°F (-36°C).
• Boiling protection up to 265°F (129°C).
• Protection against rust and other forms of corrosion.
• Proper function of calibrated gauges.
When the engine is cold, check the
level of the engine coolant in the
reservoir.
• The engine coolant should be at the FULL COLD level, or within the
COLD FILL or MIN / MAX range as listed on the engine coolant
reservoir (depending upon application).
• Refer to scheduled maintenance information for service interval
schedules.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer to Adding
engine coolant in this chapter.
Note: Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir, when the
engine is cool, until the appropriate fill level is obtained. If coolant is
filled to the COLD FILL RANGE or FULL COLD level when the engine is
not cool, the system will remain underfilled.
