Honda Goldwing Oil Change Steps
Step 1. Run the engine for a couple of minutes to heat the oil up. It'll make it a lot easier to drain.
Step 2. Remove the panel found low on the right side of the engine to expose the dipstick, which is also where you'll refill the engine with fresh oil.
Step 3. Remove the dipstick to make it easier for the old oil to drain out.
Step 4. Remove the lower cowl or fairing. There are six different Allen head screws. Keep track of them because they’re of two different lengths.
Step 5. Remove the plastic rivets near the top of the lower cowl or fairing. There are two on each side, found in the wheel well.
Step 6. Once the Allens and the plastic rivets have been removed, you can take off the cowl. Our motorcycle was on a maintenance stand that held the front wheel straight. To remove the cowl, you'll need to make sure the motorcycle is on a side stand so you can turn the wheel just enough to create the clearance you need to slide it out from behind the wheel.
Step 7. Our unit had an aftermarket panel on the bottom that we needed to remove. If your machine has one, remove it as well.
Step 8. Next, get your drain pan ready and remove the drain plug. It's found on the left side of the motorcycle to take advantage of the unit's lean when it's on the side stand.
Step 9. Inspect the end of the drain plug, which has a magnet on it to attract any metallic engine debris.
Step 10. Get your oil filter wrench and remove the oil filter. It's right near the oil drain, so you don't even have to change positions to get to it.
Step 11. Before you install the new oil filter, take a little oil and smear it around the seal at the top of the filter with your finger, then screw it into place. Honda has a torque setting for the oil filter, so set your torque wrench to 19 foot-pounds.
Step 12. Replace your drain plug and torque it to 25 foot-pounds.
NOTE: Do not overtighten the filter or the drain plug.
Step 13. Refill the engine with oil. Notice here that we now have the motorcycle off the side stand and back upright again. To accurately set the level, the motorcycle needs to be straight up, so use a maintenance stand or the center stand.
Step 14. Refill the engine through the dipstick opening. We used Honda HP4 10W40 oil since we're in a warmer climate, but if you're riding in cooler weather, you may want to choose a 30-weight oil. The most important thing is that you use a synthetic without moly in it. The engine takes about 4 quarts, so put in 3 ½ quarts, replace the dipstick, run it for a minute to move the oil around in the motor, then set the level.
Step 15. Remove the dipstick, clean it, then insert it without screwing it in. Our machine was a little low on oil, so we added a little more oil to get us right to the middle of the range on the dipstick. It was just shy of 4 quarts total to fill the engine to the correct level.
Step 16. Next, replace this lower plate if your machine has it.
Step 17. Get the motorcycle back on the side stand so you can cut the front wheel and reinstall that lower cowl/fairing.
