I wouldnt use it for top up unless you know whats already in the system


if you mix them they can turn to jelly and block waterways


forget engine ice its not worth the extra


billions of people have no trouble with normal coolant so why the need for engine ice I will never know!

Yes a full flush and use any coolant that meets the specs


I use some from euro car parts called triple QX £17 for 5 litres of concentrate this will probably do at least 3 changes


also use de ionised water its cheap enough and stops any corrosion and lime


de ionised water is cheap £3 or so for 5 litres from halfords usually called battery top up water


if you dont know whats in the bike I would flush 2 or 3 times with water then add your 50/50 coolant mix

oh and remember when flushing to fill the system and run it around in the engine to mix the coolant thats still left in this ensures its diluted as much as possible


dont boil it until it warms the radiator up will suffice that way you know your stat has opened

yup clean deionised water for every flush


some people go to the extremes of flushing the last one with 50/50 coolant


once you have done this every coolant change you do from then on can just be a straight change and no flushing


you are just making sure the old stuff is out as you dont know whats been put in in the past


best to be safe than sorry

drain the fluid through the drain bolt then replace the drain bolt


fill up with water/flush


replace rad cap run up to temp leave to cool for a bit


drain through drain bolt flush again repeating the steps above

water alone will be fine


remember not tap water! it has too much limescale in it

 

I'm planning on doing a coolant change next week, and reading through the haynes manual, it just says use a hose for the water, ie normal tap water
