Cooling System – Drain, Flush, And Refill
If the engine coolant (antifreeze) is dirty or contains a

considerable amount of sediment, clean and flush with a

reliable cooling system cleaner. Follow with a thorough

rinsing to remove all deposits and chemicals. Properly

dispose of old engine coolant (antifreeze) solution.
Refer to the “Maintenance Schedule” for the proper

maintenance intervals.
Selection Of Coolant
Use only the manufacturer’s recommended engine cool-

ant (antifreeze). Refer to “Fluids, Lubricants, and Genu-

ine Parts” in “Maintaining Your Vehicle” for further

information.

CAUTION!

Mixing of engine coolant (antifreeze) other than

specified HOAT engine coolant (antifreeze), may
result in engine damage and may decrease corro-
sion protection. If a non-HOAT engine coolant
(antifreeze) is introduced into the cooling system in
an emergency, it should be replaced with the speci-
fied engine coolant (antifreeze) as soon as possible.

Do not use water alone or alcohol-based engine

coolant (antifreeze) products. Do not use addi-
tional rust inhibitors or antirust products, as they
may not be compatible with the engine coolant
(antifreeze) and may plug the radiator.

This vehicle has not been designed for use with

propylene glycol-based engine coolant (anti-
freeze). Use of propylene glycol-based engine
coolant (antifreeze) is not recommended.
