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.
