Checking motor/electronics (M/E) coolant
The M/E coolant reservoir is located
behind the engine coolant reservoir.
Refer to the following engine
coolant sections for all information,
instructions and warnings related to
cooling systems. The two systems
use the same coolant and operate
similarly, with the Motor and
Electronics system generally
operating at a lower temperature
and pressure. The fluid levels in
both reservoirs need to be
maintained. When the engine is
cold, check the level of M/E coolant
in the reservoir.
Factory fill and coolant specifications
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.
Common instructions for cooling systems
•
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 the
scheduled maintenance information
for service interval
schedules.
•
Be sure to read and understand
Precautions when servicing your
vehicle
in this chapter.
