f4isvt Posted December 6, 2008 Report Share Posted December 6, 2008 a reverse coolant flush machine. Short of that pull the ole drain and fill. Quote Link to comment Share on other sites More sharing options...
Earache Posted December 6, 2008 Report Share Posted December 6, 2008 And make sure the coolant you add is made for aluminum radiators. Quote Link to comment Share on other sites More sharing options...
John Posted December 6, 2008 Report Share Posted December 6, 2008 about 95% of coolant nowadays IS safe for aluminum, but its doesnt hurt to read the label and doublecheck just to be sure. Quote Link to comment Share on other sites More sharing options...

RIDE!!!!!cool deali have seen on the r6 forum guys will actually run a hose through the radiator while running, and have the drain plug out y the water pump, and let it pump out.ill probably just run water through till clear like mentioned.what about some prestone radiator flush stuff??

ReconRat Posted December 7, 2008 Report Share Posted December 7, 2008 oh no, don't ever use that Prestone radiator flush. You'll never get the suds out. It will foam for hours and hours. That's my experience on a car, and I'll never do it again. I remove drain plug, disconnect both hoses, and use the garden hose to flush pressure through both radiator and block both ways. The water pump and thermostat are both obstacles, but it's better than nothing. I don't feel like removing them. Both have bypass that lets some water get past. The type of corrosion meant to be removed by reverse flushing just doesn't exist on a nice clean motorcycle engine anyway. Don't forget to drain, flush and refill the overflow reservoir also.Put plug and hoses back, fill with distilled water/coolant mix. I use Honda brand anti-freeze meant for aluminum engine.

xtremef4i Posted December 9, 2008 Report Share Posted December 9, 2008 Make sure you remove all drain bolts each time you drain/refill. Not sure about your bike, but my F4i has a drain on the water pump and a drain in the middle of the head. Drain thru all holes, put drain bolts back in, fill with water, run for a few minutes, then drain all over again untill water is clean like already mentioned. When filling bike back up with coolant, it helped me to rock the bike from side to side and give quick blips to the throttle to help work out all the air bubbles.
