Ok. I needed to top off my coolant since it was below the "Low" mark. I read about turkey basters, funnels, siphons from others who didn't want to take anything apart (no offense to those ) and I wondered "Do I really need to do it that way?"
This way took 5 minutes and all you need is a good funnel with a long neck to it. It involves removing 3 fasteners and that's it.
Step 0: Remove your seat (that's right step ZERO, because if you don't know how to do this you need to turn your bike back into Suzuki ASAP )
Step 1: Remove tank bolt.
Step 2: Move your tank back about 6" and place a board under it to keep it level and above your tank side covers. (You do not need to take you tank off!!!!)
Step 3: Remove both fasteners shown now that your tank is set back 6".
Step 4: On the top trim piece pull down and to the left to seperate the tabs connecting it to the bottom trim piece. Then slighty move the bottom trim piece out and forward about 2" which will fully expose the reserve tank.
Step 5: Pull off rubber stop from the top of the reserve tank. Insert funnel as shown and top off with 50/50 pre-mixed antifreeze.
Reverse steps to put back together.
This literally took all of about 5 minutes to do this. No mess, no dripping hoses, no cramming your hand in between the trim piece to feel around for the reserve tank top, no wondering if you put the plug back in all the way.
I hope this will work as easy for you as it did for me.
