Engine Maintenance

NOTE: The use of 50/50 percent pre-mixed
Extended Life Coolant (ELC) is recommended to
assure that de-ionized water is being used. If 100
percent full strength concentrate is used,
de-ionized or distilled water is recommended
over tap water to insure the integrity of the
cooling system is maintained.
Antifreeze Maintenance Procedure
As with all equipment containing antifreeze,
periodic inspection on a regular basis is required
to verify the condition of the antifreeze. Inhibitors
become worn out and must be replaced by
changing the antifreeze. Change ELC (red) engine
coolant every five years or 12,000 hours
(whichever occurs first).
Do not mix green or blue-green engine coolant
with ELC (red) engine coolant. See “ELC
(Extended Life Coolant)” on page 51 for more
information about ELC.
The factory recommends the use of a 50/50
antifreeze mixture in all units even if they are not
exposed to freezing temperatures. This antifreeze
mixture will provide the required corrosion
protection and lubrication for the water pump.
