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 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 starts automatically and may start at any time,
whether the engine is running or not.
• When working near the radiator cooling fan, discon-
nect 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 appli-
cable). If the engine coolant (antifreeze) is dirty, the system
should be drained, flushed, and refilled with fresh OAT
coolant (conforming to MS.90032) by an authorized 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 con-
denser.
Check the coolant recovery bottle tubing for brittle rubber,
cracking, tears, cuts, and tightness 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 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
OAT coolant (antifreeze) (conforming to MS.90032).
NOTE: If equipped with the 6.2L Supercharged engine the
intercooler must be vacuum flushed and filled. If any
coolant is needed to be added to the system please contact
an local authorized dealer.
Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
