Coolant Type
GENUINE HARLEY-DAVIDSON EXTENDED LIFE ANTIFREEZE & COOLANT (Part No. 99822-02) provides protection to -34 °F (-36.7 °C). In climates where the temperature falls below -34 °F (-36.7 °C), consult a local Buell dealer for the proper mixture.
NOTICE
Use only Genuine Harley-Davidson Extended Life Antifreeze and Coolant. Use of other coolants/mixtures may lead to motorcycle damage. (00179c)
If you find yourself in a location where Genuine Harley-Davidson Extended Life Antifreeze & Coolant is not available, you may use 50-50 mixture of de-ionized water and Ethylene Glycol-based Antifreeze.
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)
Checking Level in Coolant Sight Gauge (Quick Check)
See Figure 1. A coolant sight gauge is located inside the right radiator cowling along its outer wall. The sight gauge shows whether the coolant level is near the COLD FULL line on the expansion tank.
With the coolant cool and the motorcycle on its sidestand, look inside the right radiator cowling. If fluid is visible in the sight gauge, the coolant level is at or above the COLD FULL line.

Checking and Adding Coolant in Expansion Tank
| 1. | See Figure 2. Remove six screws from the outer shroud of the right cowling. Remove the outer shroud. | |
 WARNINGDo 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) CAUTIONAt operating temperature, radiators and oil coolers contain hot fluids. Contact with a radiator or oil cooler can result in minor or moderate burns. (00141b) | ||
| 2. | See Figure 3. Check coolant level in expansion tank with coolant cold and motorcycle on its sidestand. NOTE Only fill coolant into expansion tank. Do NOT remove cap from the radiator. See a Buell dealer if additional cooling system service is required. | |
| 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) | ||
| 3. | If level is below COLD FULL line on tank, remove cap from expansion tank. Add HARLEY-DAVIDSON EXTENDED LIFE ANTIFREEZE & COOLANT (Part No. 99822-02) until fluid level reaches the COLD FULL line. NOTE Genuine Harley-Davidson Extended Life Antifreeze & Coolant is pre-diluted and ready to use full-strength. Do NOT add water. | |
| 4. | Replace the cap on the expansion tank. | |
| 5. | Install outer shroud on right radiator cowling. Tighten six screws to 9–9.9 N·m (80–88 in-lbs). NOTE If the coolant expansion tank is empty when the engine is cold, it is possible that air has been drawn into the cooling system. The system must be purged of any trapped air and refilled with coolant. See the service manual for instructions on the correct procedure. |
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)
