2018 Burgman 400 radiator cap access

I've recently purchased a 2018 burgman 400. It didn't come with a manual. I've found videos for access to the radiator. But, can't find anything for my model. Can someone help me to get to the radiator cap to check coolant level. The reservoir above the gas cap is empty. The bike only has 1000 miles on it. I sure don't want to run it with low coolant and overheat it.

I just did a coolant flush on my 2018 400 a couple of weeks ago and it's quite elaborate. I had to disassemble half the bike. The radiator cap is located under the dash and instrement cluster just left of the steering. You will need to remove, the front cowling, the windshield, the dash cover ontop of the instrument cluster, and a couple allen bolts in the cockpit to the sides on the instrument cluster.. I removed both upper and lower handlebar plastics. Then, I think there are two more screws keeping the instrument cluster in place along with some rubber poitns that are behind the instrument cluster that mount into rubber holes with the rubber points facing forward toward the headlights.

Once everything holding the instrument cluster to the dash is unscrewed and the top of the dash is removed, you can pull the instrument cluster out of the rubber holes by pulling the cluster toward the seat. You don't have to detach any electrical wiring, you can just more the the instrument cluster out of the way. At that point you should be able to see about half the radiator cap. on the left side as you sit on the bike.

You can see a Mitch's Scooter You Tube video on an older model,doing a coolant flush but the difference with the 2018 model is that the 2018 doesn't have a seperate front dash piece of plastic that pops out directly below the steering column facing the driver above the ignition. which is the last piece Mitch removes to access the radiator cap. However on our 2018 model there is no separate plastic piece that pulls out and that through me for a loop. Our plastic that acts as a frame for the front dash that you see when sitting on the bike that wraps around both glove boxes,, the emergency brake,, the ignition, and all the way to the fuel door is one solid piece,. Hence the need to remove the windshield, dash cover, and instrument cluster to access the radiator cap.

Once you see the cap, on the left center as you sit on the bike it is still almost half blocked by the big plastic panel described above. There is a screw, that keeps the radiator cap assembly in place bolted to a metal bracket with a small hose attached with a metal clip holding the hose in place. Unscrew the screw on top of the bracket and remove the clip and small hose, the radiator cap assembly will then freely move but still be attached to the main radiator hose, but at least you can then unscrew the cap, remove the cap, see into it and if necessary add coolant. Again, I recomend Mitch's video on You Tube where he shows how to do a complete flush and get any air bubbles trapped out.

I hope that helps, it is rather difficult to explain, I gave it my best shot from memory.
