jamesd1981 Posted January 25, 2015 Share Posted January 25, 2015 Can anyone confirm if this prestone coolant is suitable for motorcycles - http://www.amazon.co.uk/Prestone-Antifr ... B004R95MBCSeems to tick all the boxes with corrosion protection and suitable for aluminium radiators. Quote Link to comment Share on other sites More sharing options...
Stu Posted January 25, 2015 Share Posted January 25, 2015 Yup it will be fine as will all other coolants out there You will need more than 1 litre though! Quote Link to comment Share on other sites More sharing options...
jamesd1981 Posted January 25, 2015 Author Share Posted January 25, 2015 Thanks stu, it's only for a top up at the moment, going to use engine ice next time i do a full flush Quote Link to comment Share on other sites More sharing options...
Stu Posted January 25, 2015 Share Posted January 25, 2015 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!

jamesd1981 Posted January 25, 2015 Author Share Posted January 25, 2015 I don't not flushed the coolant since i bought the bike in march, so you recommend a full flush then stick with prestone Quote Link to comment Share on other sites More sharing options...
Stu Posted January 25, 2015 Share Posted January 25, 2015 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 Quote Link to comment Share on other sites More sharing options...
jamesd1981 Posted January 25, 2015 Author Share Posted January 25, 2015 Great thanks Stu, I will do a thorough flush and refill with prestone and just stick to using that Quote Link to comment Share on other sites More sharing options...
jamesd1981 Posted January 25, 2015 Author Share Posted January 25, 2015 Just watched a youtube tutorial on flushing your radiator which says on first flush use 50/50 mix of water and vinegar ? is this necessary or will water alone suffice.

Stu Posted January 25, 2015 Share Posted January 25, 2015 water alone will be fine remember not tap water! it has too much limescale in it Quote Link to comment Share on other sites More sharing options...
Stu Posted January 25, 2015 Share Posted January 25, 2015 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 Quote Link to comment Share on other sites More sharing options...
jamesd1981 Posted January 25, 2015 Author Share Posted January 25, 2015 Yes will use deionised water, should I use clean water on every flush ? Quote Link to comment Share on other sites More sharing options...
Stu Posted January 25, 2015 Share Posted January 25, 2015 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 Quote Link to comment Share on other sites More sharing options...
jamesd1981 Posted January 25, 2015 Author Share Posted January 25, 2015 Do you remove the drain bolt or radiator cap first, youtube has some conflicting videos Quote Link to comment Share on other sites More sharing options...
Stu Posted January 25, 2015 Share Posted January 25, 2015 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 Quote Link to comment Share on other sites More sharing options...

mealexme Posted January 26, 2015 Share Posted January 26, 2015 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 Quote Link to comment Share on other sites More sharing options...
Stu Posted January 26, 2015 Share Posted January 26, 2015 That's up to you but I wouldn't Just because Haynes says it it doesn't mean it's right Quote Link to comment Share on other sites More sharing options...
