Cooling System — Drain, Flush, And Refill
The cooling system should be drained, flushed, and
refilled, at the intervals shown on the Maintenance
Schedule. Refer to Section 8 of this manual.
If the solution is dirty and contains a considerable
amount of sediment, clean and flush with reliable cooling
system cleaner. Follow with a thorough rinsing to remove
all deposits and chemicals. Properly dispose of old
antifreeze/coolant solution.
Discard old antifreeze/coolant solution according to rec-
ommended procedure.
Selection Of Engine Coolant
Use only the manufacturer’s recommended antifreeze/
coolant. Refer to Fluids, Lubricants, and Genuine Parts in
this section for correct antifreeze/coolant type.
CAUTION!
•
Mixing of antifreeze/coolants other than the speci-
fied HOAT antifreeze/coolants, may result in en-
gine damage and may decrease corrosion protec-
tion.
If
a
non-HOAT
antifreeze/coolant
is
introduced into the cooling system in an emer-
gency, it should be replaced with the specified
antifreeze/coolant as soon as possible.
•
Do not use plain water alone or alcohol-base
antifreeze/coolant products. Do not use additional
rust inhibitors or antirust products, as they may
not be compatible with the antifreeze/coolant and
may plug the radiator.
•
This vehicle has not been designed for use with
Propylene Glycol based antifreeze/coolants. Use
of Propylene Glycol base antifreeze/coolants is not
recommended.
