Where is the radiator filler on Kawasaki Vulcan 800?

Hey there, if you want to top up or refill the radiator you will need to remove the seat and gas tank. The filler cap is on top of the thermostat housing positioned under the tank just above the engine. If you are refilling the radiator, you will need to run the engine till all the little air bubbles clear. This is the system self bleeding. Once the bubbles go, refit the cap and reassemble the bike.

Happy road miles,
