Vehicle Care
Check to see if coolant is visible in
the high voltage battery coolant
reservoir. If coolant is visible but the
coolant level is below the cold fill
line, there could be a leak in the
cooling system.
Cooling System (TPIM,
APM, and Charger
Modules)
The Traction Power Inverter Module
(TPIM), Accessory Power Module
(APM), and Charger module are
cooled using a separate
coolant loop.
The TPIM, APM, and charger
modules in the vehicle are kept
below a maximum temperature.
If the temperature rises above this
temperature, the electric cooling fan
will turn on and cool the coolant
until the correct temperature is
reached.
What to Use
The TPIM, APM, and charger
module coolant reservoir in the
vehicle is filled with a 50/50 mixture
of DEX-COOL coolant and
deionized water. If using this
mixture, nothing else needs to be
added.
The coolant needs to be replaced
at the appropriate interval. See
Maintenance Schedule on
page 11-2
.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The TPIM, APM, and charger
module coolant reservoir is in the
underhood compartment. See
Underhood Compartment Overview
on page 10-6
