Cooling System - Chrysler Pacifica 2021 Owner's Manual

To minimize the possibility of catalytic converter
damage:
Do not interrupt the ignition when the transmis-

sion is in gear and the vehicle is in motion.
Do not try to start the vehicle by pushing or

towing the vehicle.
Do not idle the engine with any ignition compo-

nents disconnected or removed, such as when
diagnostic testing, or for prolonged periods
during very rough idle or malfunctioning oper-
ating conditions.

WARNING!
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 radi-
ator or coolant bottle is hot.
Keep hands, tools, clothing, and jewelry away

from the radiator cooling fan when the hood is
raised. The fan starts automatically and may
start at any time, whether the engine is
running or not.
When working near the radiator cooling fan,

disconnect the fan motor lead or turn the igni-
tion to the OFF mode. The fan is temperature
controlled and can start at any time the igni-
tion is in the ON mode.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine coolant is
dirty, the system should be drained, flushed, and
refilled with fresh Organic Additive Technology
(OAT) coolant (conforming to MS.90032) by an
authorized dealer. Check the front of the A/C
condenser for any accumulation of bugs, leaves,
etc. If dirty, clean by gently spraying water from a
garden hose vertically down the face of the
condenser.
Check the engine cooling system hoses for brittle
rubber, cracking, tears, cuts, and tightness of the
connection at the coolant recovery bottle and
radiator. Inspect the entire system for leaks. DO
NOT REMOVE THE COOLANT PRESSURE CAP
WHEN THE COOLING SYSTEM IS HOT.

SERVICING AND MAINTENANCE
Cooling System — Drain, Flush And Refill
NOTE:
Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly
could lead to severe internal engine damage. If any
coolant is needed to be added to the system
please contact an authorized dealer.
If the engine coolant (antifreeze) is dirty or
contains visible sediment, have an authorized
dealer clean and flush with Organic Additive
Technology (OAT) coolant (conforming to
MS.90032).

NOTE:
Mixing of engine coolant (antifreeze) other than

specified Organic Additive Technology (OAT)
engine coolant, may result in engine damage
and may decrease corrosion protection. OAT
engine coolant is different and should not be
mixed with Hybrid Organic Additive Technology
(HOAT) engine coolant or any "globally compat-
ible" coolant. If a non-OAT engine coolant is
introduced into the cooling system in an emer-
gency, the cooling system will need to be
drained, flushed, and refilled with fresh OAT
coolant (conforming to MS.90032), by an autho-
rized dealer as soon as possible.
