Cooling System – Drain, Flush,And Refill
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
If the solution 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 the old engine coolant (antifreeze) solution.
Selection Of Coolant – Gasoline Engine
Use only the manufacturer's recommended coolant.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Technical Specifications” for further information.
• Mixing of coolants other than specified
engine coolants (antifreeze), may result
in engine damage and may decrease cor-
rosion protection. If a non-specified coolant (an-
tifreeze) is introduced into the cooling system in
an emergency, it should be replaced with the
specified coolant (antifreeze) as soon as possible.
• Do not use plain water alone or alcohol-based
engine coolant (antifreeze) products. Do not use
additional rust inhibitors or antirust products, as
they may not be compatible with the radiator
engine coolant (antifreeze) and may plug the
radiator.
