                            NOTICE

Use only Genuine Harley-Davidson Extended Life
Antifreeze and Coolant. Use of other coolants/mixtures
may lead to motorcycle damage. (00179c)

GENUINE         HARLEY-DAVIDSON         EXTENDED        LIFE
ANTIFREEZE AND COOLANT is pre-diluted and ready to use
full strength. It provides temperature protection to -34.0 °F
(-36.7 °C). DO NOT add water.

                            NOTICE                                            Figure 2-21. Coolant Filler Cap/Dipstick

De-ionized water must be used with the antifreeze in the
cooling system. Hard water can cause scale accumulation
in water passages which reduces cooling system
efficiency, leading to overheating and motorcycle damage.
(00195b)

                          A WARNING

Do not loosen or remove pressure cap when cooling
system is hot. The cooling system is under pressure and
hot coolant and steam can escape from pressure cap,
which could cause severe burns. Allow motorcycle to cool
before servicing the cooling system. (00091c)

                             NOTE
If the coolant reservoir is low when the motorcycle is cold,                                   NOTICE
inspect the system for leaks. Repair as needed. Fifi system
