You still have to follow the spesification spesified for each fluids, otherwise you end up ruining your engine....It does not have to be Honda specific... Just like the motor oil. Of course Honda is going to tell you you have to use their own. I just buy the green 50/50 mix.
Must be suitable for aluminum engines as you stated but must also be silicate free.Hi all - in the manual, it says "Pro Honda HP Coolant" which I can find on ebay, but only in the USA !! (I'm in the UK)
Guidelines are a concentration of 50 / 50 anti-freeze and distilled water, which must be suitable for aluminium engines.
I'll report back when I find one.
Thank you - I've just got some CASTROL motorcycle coolant and some distilled water; £7.50 for both which is a really good price! I'm sure it'll be fine - it was sold to me by a guy who puts it in his own bikes so . . . what could possibly go wrong!Don't be tempted to just top up with neat coolant, it'll raise the freezing temperature. The weaker 50/50 mix helps maintain a lower freezing point than just neat antifreeze.
the Castrol coolant already comes pre-diluted at a 50/50 mix...you do not want to add distilled waterThank you - all comments greatly appreciated!
I've found Castrol Motorcycle Coolant for £6.50 from my local Wilko Motosave, and a bottle of distilled water for £1 - all sold to me by a chap who uses it in his own bikes! What could possibly go wrong . . .
