WARNING
Coolant mixture contains toxic chemicals, which may be fatal if swallowed. If swallowed, do not induce vomiting; call a physician immediately. Use in a well ventilated area. Irritation to skin or eyes can occur from vapors or direct contact. In case of skin or eye contact, flush thoroughly with water and go to hospital, if necessary. Dispose of used coolant according to federal, state and local regulations. (00092a)
CAUTION
At operating temperature, radiators and oil coolers contain hot fluids. Contact with a radiator or oil cooler can result in minor or moderate burns. (00141b)
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 -36.7 °C (-34 °F). DO NOT add water.
NOTICE
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)
If GENUINE HARLEY-DAVIDSON EXTENDED LIFE ANTIFREEZE AND COOLANT is unavailable, a mixture of de-ionized water and ethylene glycol-based antifreeze may be used. At the first opportunity, change back to GENUINE HARLEY-DAVIDSON EXTENDED LIFE ANTIFREEZE AND COOLANT.
Checking Coolant Level
NOTE
Check coolant level with engine cold and motorcycle on level ground.
    NOTE
    Use a light source from opposite side of reservoir to view coolant level.
  1. See Figure 1. Check that coolant level in reservoir is between the coolant maximum level mark (1) and the coolant cold level mark (3).
    2. NOTE
    • Do not remove the reservoir pressure cap (2).
    • If the coolant reservoir is empty when the engine is cold, inspect the system for leaks. Repair as needed. Fill system with coolant and perform bleed procedure. See a Harley-Davidson dealer for service.
  2. If level is below coolant cold level mark (3) line on tank, add GENUINE HARLEY-DAVIDSON EXTENDED LIFE ANTIFREEZE AND COOLANT until fluid level reaches, or is slightly above the "COLD" line.
Add Coolant
  1. Allow engine to cool.
  2. Remove reservoir from clip.
  3. See Figure 1. Remove reservoir pressure cap (2).
  4. Hold reservoir vertical.
  5. Add GENUINE HARLEY-DAVIDSON EXTENDED LIFE ANTIFREEZE AND COOLANT until fluid level reaches, or is slightly above the coolant cold level mark (3).
  6. Install reservoir pressure cap.
  7. Replace reservoir in clip.

Clean Radiator
NOTICE
Clean the inlet surface of the radiator regularly. Leaves and other debris can collect on the radiator surface and degrade radiator performance which could lead to overheating and motorcycle damage. (00197d)
Models Without Fairing Lowers
  1. See Figure 2. Remove chin spoiler.
    1. With motorcycle on jiffy stand, turn forks to the left.
    2. Pull chin spoiler (1) straight forward.
  2. Clean debris from radiator (3) fins.
  3. Install chin spoiler.
    1. With motorcycle on jiffy stand, turn forks to the left.
    2. Lubricate barbed studs on chin spoiler.
    3. Align barbed studs on chin spoiler with grommets (3).
    4. Push in to secure.
