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
(such as the Rotunda Battery and Antifreeze Tester, 014–R1060). The
level of coolant should be maintained at the bottom of the lower baffle 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.
•
Enables calibrated gauges to work properly.
1. Engine coolant reservoir
2. Intercooler coolant reservoir
When the engine is cold, check the
level of the engine coolant in the
reservoir.
•
The engine coolant level should be at the bottom of the lower baffle in
the coolant reservoir.
•
Refer to the
Scheduled Maintenance Guide
chapter for service
interval schedules.
•
Be sure to read and understand
Precautions when servicing your
vehicle
in this chapter.
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.
