Cooling System — Drain, Flush, And Refill
At the intervals shown on the Maintenance Schedule, the
system should be drained, flushed and refilled. 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.
Selection Of 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/coolant, other than the specified
HOAT antifreeze/coolant, may result in engine dam-
age and may decrease corrosion protection. If a
non-HOAT antifreeze/coolant is introduced into the
cooling system in an emergency, it should be re-
placed 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/coolant. Use of
Propylene Glycol-based antifreeze/coolant is not
recommended.
