| 1. | See Figure 1. Install the oil cooler (2) to the frame with three clamps (4), three socket head screws (1), three nuts (5) and six washers (3) from the kit. Orient the clamps flat side forward and on the forward side of the oil cooler. Tighten the three oil cooler mounting screws to 10.9–13.5 N·m (96–120 in-lbs). | |||||||||||
| 2. | See Figure 2. Remove the spin-on oil filter and oil filter adapter (1) from oil filter mount location. Clean the oil filter mounting area thoroughly. Discard oil filter and adapter. NOTE The oil cooler adapter assembly has two flanges protruding out of the back side. The flanges must be installed toward the oil filter mounting location and through the oil adapter gasket. |

| 3. | See Figure 3. From the kit, install the oil cooler adapter gasket (3) onto the oil cooler adapter assembly (1). The oil cooler adapter assembly flanges should be aligned so it is installed into the oil adapter cooler gasket cutout as shown. NOTE Due to the locating flanges, the oil cooler adapter assembly and gasket will only install properly in one position on the oil filter mounting surface. | |||||||||||
| 4. | See Figure 3. Install the oil cooler adapter assembly and gasket onto the oil filter mounting surface of the engine with the mounting fitting (2). Verify adapter locates properly in the mounting surface. Verify the raised lip of the mounting fitting faces the adapter assembly. Tighten mounting fitting to 16.3–21.7 N·m (12–16 ft-lbs).

| 6. | Fasten hoses to oil cooler adapter and oil cooler with worm drive clamps (6). Tighten clamps to 0.9 N·m (8 in-lbs). | |||||||||||
| 7. | Lubricate a new oil filter's seal with new engine oil. Thread filter on until seal touches mounting surface, then turn an additional 1/2 to 3/4 turn. NOTE Position the clamps to avoid interference with oil filter installation. Check that hose routing is clear of the oil filter and sharp edges. The hoses must be free of bends or kinks that could obstruct oil flow. | |||||||||||
| 8. | Verify all cables and harnesses are clear of the oil cooler adapter, in order to prevent wear. | |||||||||||
| 9. | Thoroughly clean the oil cooler of all dirt, grease and wax with isopropyl alcohol. Use the alcohol to clean the chrome oil cooler cover as needed. Allow to dry. |  Figure 4. Apply Sealant Inside Chrome Cover | ||||||||||
| 10. | See Figure 4. Apply sealant to the inside of the chrome cover as shown, at the upper and lower corners. NOTE Be careful to avoid getting sealant on the oil cooler cooling fins. Do not operate the motorcycle for 24 hours to allow the sealant to fully cure. | |||||||||||

System Flow Test
2005 & Later Models or Models with Later Style Dipsticks
NOTICE
Oil level cannot be accurately measured on a cold engine. For pre-ride inspection, with motorcycle leaning on jiffy stand on level ground, oil should register on dipstick between arrows when engine is cold. Do not add oil to bring the level to the FULL mark on a COLD engine. (00185a)
2004 & Earlier Models
NOTICE
Oil level cannot be accurately measured on a cold engine. For pre-ride inspection with the motorcycle upright (not leaning on jiffy stand) on level ground, the oil should register approximately at the midpoint of the cross-hatch area on the dipstick when the engine is cold. Do not add oil to bring the level to the full mark on a cold engine. (00186b)
NOTICE
Do not operate the engine when the oil level is below the add mark on the dipstick at operating temperature. Engine damage will result. (00187b)
| 1. | Start engine. Examine all hose connections for leaks. If there is no leakage, allow engine to warm up. NOTE Position the clamps to avoid interference with oil filter installation. Check that hose routing is clear of the oil filter and sharp edges. The hoses must be free of bends or kinks that could obstruct oil flow. | |
| 2. | Verify that temperature of oil cooler increases when engine reaches normal operating temperatures. If the oil cooler remains cool after engine has warmed up, there may be an oil obstruction. Turn off engine and check system for source of obstruction. | |
| 3. | After engine has cooled, re-tighten all hose clamps to 0.9 N·m (8 in-lbs). | |
| 4. | Fill oil to FILL level on dipstick. |
