ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
intervals listed in
scheduled maintenance information.
The coolant
concentration should be maintained at 50/50 coolant and distilled water,
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 RANGE as listed on the engine coolant reservoir
(depending upon application).
•
Refer to
scheduled maintenance information
for service interval
schedules.
•
Be sure to read and understand
Precautions when servicing your
vehicle
in this chapter.
