Be sure to carefully clean the front surface of the radiator regularly. Leaves and other debris can collect on the radiator surface and degrade radiator performance. This could lead to engine overheating and engine damage.

1. Cover front fender with a shop towel or protective cover.

2. See Figure 6-20. Hold radiator/oil cooler assembly up to frame and thread on oil line sleeves (18).

3. Thread on but do not tighten nuts (J0) holding radiator/oil cooler assembly to engine mount studs (1).

NOTE

The oil lines should be angled and routed so there is no interference between the radiator fans and the oil lines when the radiator is in place on the frame.

4. See Figure 6-21. While holding each oil line fitting (oil in & oil out) with an angled wrench, install and tighten oil line sleeves to 53-58 Nm (39-42 ft-lbs).

5. See Figure 6-20. Slip cross member (26) over grommets (22) on radiator mounting pins. Install cross member to frame.

6. Tighten cooling system fasteners to following:

a. Cross member fasteners to 20-26 Nm (15-19 ft-lbs).

b. Top mounting nuts (10) to 19-27 Nm (15-20 ft-lbs).

7. Route drain hose (4) to overflow bottle.

8. Install radiator cover.

9. Connect:

a. Crank position sensor connector [79], b. Top and bottom fan power connectors [97T], [97B].

c. Stator to voltage regulator connector [46],

10. Install left and right side radiator covers.

11. Fill engine with oil. See 1.6 ENGINE OIL AND FILTER.

12. install air filter bottom, velocity stacks, o-rings and breather hose. See 1.4 AIRBOX AND AIR FILTER.

13. Loosen air bleed plug. Fill with GENUINE HARLEY-DAVIDSON EXTENDED LIFE ANTIFREEZE & COOLANT through filler neck. See 6.3 ENGINE COOLANT.

14. Tighten air bleed plug to 9-11 Nm (80-97 in-lbs). and replace pressure cap.

15. Install air filter, air filter top and air filter cover. See 1.4 AIRBOX AND AIR FILTER.

Always connect the positive battery cable first. If the positive cable should contact ground with the negative cable installed, the resulting sparks may cause a battery explosion that could result in death or serious injury.

16. Replace the negative battery cable. Tighten to 6.8-10.8 Nm (60-96 in-lbs).

17. Install right side cover and maxi-fuse.

18. After running engine, inspect oil sleeves and fittings for oil leaks. Check oil level and add oil if required.

19. After running engine, check coolant level in overflow bottle with coolant cold with motorcycle on jiffy stand. If level is below COLD FULL line, remove cap from overflow bottle and add antifreeze until fluid level reaches COLD FULL line.

20. Continue to run engine, check level, and add antifreeze until fluid level remains at COLD FULL line with motorcycle on jiffy stand.
