Check the Power Electronics and Battery Thermal Man-
agement Systems coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable).
Maintain coolant (antifreeze) concentration at a mini-
mum of 50% Mopar Antifreeze/Coolant 10 Year/
150,000 Mile Formula OAT (Organic Additive Technol-
ogy) and distilled/deionized water for proper corrosion
protection.
Check the coolant bottles tubing for brittle rubber,
cracking, tears, cuts and tightness of the connection at
the bottles and radiator. Inspect the entire system for
leaks.
Check the front of the A/C condenser for any accumu-
lation of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically down the
face of the condenser.
NOTE:DO NOT REMOVE THE COOLANT PRES-
SURE CAP WHEN THE COOLING SYSTEM IS HOT.
WARNING!
You or others can be badly burned by hot coolant
(antifreeze) or steam from your radiator. If you see
or hear steam coming from under the hood, do not
open the hood until the radiator has had time to
cool. Never try to open a cooling system pressure
cap when the radiator is hot.

Power Electronics And Battery Thermal
Management Systems — Drain, Flush And Refill
Refer to “Maintenance Schedules” for the proper main-
tenance intervals.
If the coolant (antifreeze) is dirty or contains a consid-
erable amount of sediment, clean and flush with a
reliable cooling system cleaner. Follow with a thorough
rinsing to remove all deposits and chemicals. Properly
dispose of old coolant (antifreeze) solution.
CAUTION!
It is recommended to have the cooling systems
serviced at your authorized dealer. Failure to do so
could result in poor cooling system performance
and/or vehicle damage.
Disposal Of Used Power Electronics And
Battery Thermal Management Systems Coolant
Used antifreeze is a regulated substance requiring
proper disposal. Check with your local authorities to
determine the disposal rules for your community. To
prevent ingestion by animals or children, do not store
antifreeze in open containers or allow it to remain inpuddles on the ground. If ingested by a child, contact a
physician immediately. Clean up any ground spills
immediately.
Points To Remember
WARNING!
•
Turn vehicle OFF and disconnect the fan motor
lead before working near the radiator cooling fan.
• You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the
hood, do not open the hood until the radiator has
had time to cool. Never open a cooling system
pressure cap when the radiator or coolant bottle is
hot.
• Keep hands, tools, clothing, and jewelry away
from the radiator cooling fan when the hood is
raised. The fan may start without warning,
whether the ignition is on or off.
If an examination of your underhood compartment
shows no evidence of cooler or hose leaks, the vehicle
may be safely driven.
• Do not overfill the coolant recovery bottles.
