•
Do not idle the engine with any spark plug
wires disconnected or removed, such as
when diagnostic testing, or for prolonged
periods during very rough idle or malfunction-
ing operating conditions.
NOTE:
Your vehicle’s exhaust system may be equipped
with an Electronic Exhaust Valve (EEV) system,
if the exhaust system is replaced with aftermar-
ket products a Malfunction Indicator Lamp (MIL)
will illuminate.
Cooling System
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 pres-
sure 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 starts automati-
cally and may start at any time, whether the
engine is running or not.
(Continued)
WARNING! (Continued)
•
When working near the radiator cooling
fan, disconnect the fan motor lead or turn
the ignition to the OFF mode. The fan is
temperature controlled and can start at any
time the ignition is in the ON mode.
Coolant Checks
Check engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine cool-
ant (antifreeze) is dirty, the system should be
drained, flushed, and refilled with fresh OAT
coolant (conforming to MS.90032) by an autho-
rized dealer. Check the front of the radiator 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 coolant recovery bottle tubing for
brittle rubber, cracking, tears, cuts, and tight-
ness of the connection at the 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 cool-
ant properly. Failure to fill these systems prop-
erly could lead to severe internal engine dam-
age. 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 (anti-
freeze) (conforming to MS.90032).
Refer to the “Service And Warranty Handbook”
for the proper maintenance intervals.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
NOTE:
•
Mixing of engine coolant (antifreeze) other
than specified Organic Additive Technology
(OAT) engine coolant (antifreeze), may result
in engine damage and may decrease corro-
sion protection. Organic Additive Technology
(OAT) engine coolant is different and should
not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (anti-
freeze) or any “globally compatible” coolant
(antifreeze). If a non-OAT engine coolant
(antifreeze) 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 (antifreeze) products. Do not
use additional rust inhibitors or antirust prod-
ucts, as they may not be compatible with the
radiator engine coolant and may plug the
radiator.
