All water cooled engines are shipped from the factory with a 50 percent permanent type
antifreeze concentrate and 50 percent water mixture in the engine cooling system.
This provides the following:
1. Prevents freezing down to -30 F (-34 C).
2. Retards rust and mineral scale that can cause engine overheating.
3. Retards corrosion (acid) that can attack accumulator tanks, water tubes, radiators, and core
plugs.
4. Provides lubrication for the water pump seal.
Extended Life Coolant (ELC)
ELC is used in this unit. A nameplate near the coolant expansion tank identifies units with ELC.

e:: 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.
