I'm getting ready for track and want to flush the old coolant out the bike and replace it with Water Wetter. My question is when flushing the coolant can I use a garden hose (tap water) to get the old stuff out or, should I use distilled water? Also, the manual says it takes 2.9 quarts to fill the radiator. That means I need 10-12 capsful of Water Wetter added to the 2.9 quarts of distilled water right?

I have done it both ways, but you really should use distilled water, tap water has too many minerals and shit in it that cause deposits and stuff in your radiator. I just switched over to engine ice and did a complete flush with distilled.

I would use distilled water. Of course tap will work but it will leave deposits in the internals that will corrode the system faster. And how much ever that manual says it holds is what it holds... not including the water wetter. I would mix the water wetter into somthing that measures exactly what you need for full capacity and add your water to that to equal exactly what the capacity is then add ALLLLL of it to the system. Making sure to get alllll air out of the system.

how would you go about making sure you have all the air out??
Well I'm sure there are tools to get it done faster but I' m poor so I don't have those,:rofl:
I just get a container and measure out the full capacity of the bike into that container with measuring cups, then put a peice of tape around the container marking the full cpacity spot then fill the container with any additives I'm putting in first then fill the rest of the way up with antifreeze or water etc... then I just keep slowly filling the bike until ALLLLLLL of it goes in with out pouring over. Most of it in without the motor running some with the motor running and more with it off. Till it all goes in, and if any spills I estimate the amount and add more.
Air in the system = problems.

Just take a gallon of distilled water, read the label and add the correct amount of Water Wetter to the gallon. You will not use the entire gallon obviously so the rest of the pre-mix you can bring to the track as extra...you may even be able to help a fellow trackday rider. As for the air in the cooling system, I just fill to almost the top, hit the starter a couple times just to get the motor to turn over and circulate the new coolant. Add a little each time. I then will lean the bike side to side slowly, add a little, and hit the starter a couple more times. Never had a problem doing this method.

As for Engine Ice, PLEASE DO NOT ride your bike on the track with that shit. It is worse than regular anti-freeze if spilled. It is banned by club level racing organizations and all pro organizations for a reason. It it glycol based and it sucks. I have personally seen one trackday noob leak Engine Ice in the chicane at a track and the next 4 bikes crashed into a big pile. Track staff tried oil dry and tractors with scrubbers to get that shit off the track. After about an hour delay we got back on the track only to have the first two bikes crash in the same spot. All because some asshat didn't follow the rules of the track and drain the Engine Ice and use either distilled water or distilled water with Redline (aka: Water Wetter)

I have 08 750 with a 1000 miles on it. Should I change the coolant and use the water wetter and distilled water or buy the redline supercool. I am assuming that the coolant in the bike is from Japan and has been in there for almost 2 years now right?

Thanks!!

anti freeze is not the best coolant. It is there to protect from guess what....... Freezing :)

distilled water and water wetter has droped running temps on all my bikes some more then others. With my gsxr it was about 5 degrees F.
