Chrysler Pacifica Hybrid 2018, Owner'S Manual, Page: 469 / 617

NOTE:
•
Mixing coolant (antifreeze) types is not recommended
and can result in cooling system damage. If HOAT and
OAT coolant are mixed in an emergency, have a autho-
rized dealer drain, flush, and refill with OAT coolant
(conforming to MS.90032) as soon as possible.
•
Low pressure expansion bottles for power electronics
and battery cooling require a special tool for removing
the cap from the expansion bottle. For the battery
coolant bottle, it is important to not add coolant if level
is low. The vehicle should be taken to dealer for proper
servicing of the battery coolant loop if this should occur.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that engine coolant
(antifreeze) will return to the radiator from the coolant
expansion bottle/recovery tank if so equipped.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
•
Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is over-
heated. Do not loosen or remove the cap to cool an
overheated engine. Heat causes pressure to build up
in the cooling system. To prevent scalding or injury,
do not remove the pressure cap while the system is
hot or under pressure.
•
Do not use a pressure cap other than the one speci-
fied for your vehicle. Personal injury or engine
damage may result.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is a regu-
lated 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 ethylene glycol-based coolant in open contain-
ers or allow it to remain in puddles on the ground. If
ingested by a child or pet, seek emergency assistance
immediately. Clean up any ground spills immediately.
