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.
NOTE:
If the engine coolant protection is changed, you
must also adjust the coolant protection for the
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.
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 or
electrical system 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 OAT coolant
(conforming to MS.90032).
For proper maintenance intervals
Electric/Battery Coolant System
These coolant systems must be serviced by an
authorized dealer. If the coolant level is below
what is specified on the reservoir, contact an
authorized dealer for service.
These systems require the use of high purity
water, such as deionized, or distilled water,
when mixing the water and coolant (antifreeze)
solution. The use of lower quality water will
reduce the amount of corrosion protection in
the cooling systems. If the coolant level of the
battery coolant system is low, the wrench
warning light will be illuminated on the
instrument cluster.
Selection Of Coolant
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 compatible”
coolant. If a non-OAT engine coolant is introduced
into the cooling system in an emergency, the
cooling system will need to be drained, flushed,
and refilled with fresh OAT coolant (conforming to
MS.90032), by an authorized dealer as soon as
possible.
Do not use water alone or alcohol-based
engine coolant products. Do not use addi
-
tional rust inhibitors or antirust products, as
they may not be compatible with the radiator
engine coolant and may plug the radiator.
