Easy Radiator Filling Procedure
Recently, I noticed that antifreeze was coming from my radiator. When I got home, I checked the reason(s) for the leak. Without removing anything from the bike I found that the top crossover hose clamp (left radiator) was not tight and was causing the leak. The hose was in good shape, so I easily tightened the clamp. I realized that the next step was to re-fill the radiator. I listened to the video on You Tube regarding changing antifreeze, I read my Clymer manual and reviewed this forum related to radiator leaks. I learned that I would need as a minimum to remove the left side panel. Having removed the Tupperware when I did previous maintenance (installing new fuel and air filters, installing brake hoses, etc.) I was familiar with the procedure. I put the motorcycle on the center stand and reviewed the status of the radiator cap. I found that I could easily remove the radiator cap (I have large hands and am not very strong) without removing any panels. I took the cap off and took it to Auto Zone to check the status of the cap – PSI was ok. Without removing any panels, I filled the radiator using the following procedure:
1. Removed the left signal light assenbly (1 screw)
2. Attached a rubber hose to a funnel and put hose through the signal light opening to the radiator
3. Had my wife put antifreeze (50/50%) into the funnel while I held the hose into the radiator – she stopped when antifreeze leaked from the radiator
4. Without the cap installed, I ran the engine for several minutes and compressed the top hose (to get the air out of the system). After turning the engine off, I added a small amount of antifreeze and easily re-installed the radiator cap. I also re-filled the over flow tank.
The next time I change the antifreeze I will be using this method. I hope this information is helpful!
