Jeep 2005 Liberty - Manual (Page 326)

Cooling System — Drain, Flush, And Refill
At the intervals shown on the appropriate “Maintenance
Schedule” the system should be drained, flushed, and
refilled.
If the coolant solution is dirty or contains a considerable
amount of sediment, clean and flush with a reliable
cooling system cleaner (see your authorized dealer for
recommendations). Follow with a thorough rinsing to
remove all deposits and chemicals. Properly dispose of
old antifreeze/coolant solution.
Selection Of Engine Coolant
Use only the manufacturer’s recommended antifreeze/
coolant, refer to Recommended Fluids, Lubricants, and
Genuine Parts for correct antifreeze/coolant type.
CAUTION!
• Mixing of antifreeze/coolant other than the speci-
fied HOAT antifreeze/coolant may result in de-
creased corrosion protection and engine damage.
If a non-HOAT antifreeze/coolant is introduced
into the cooling system in an emergency, 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/coolant. Use of
Propylene Glycol base antifreeze/coolant is not
recommended.
