I'm looking to change the coolant in my PCX as it is not long until I've had it for 2 years.
I was in Halfords looking for the required coolant but the only advise i got there was "can't help with a motorbike"
COOLANT
Coolant Recommendation
The owner must properly maintain the
coolant to prevent freezing, overheating,
and corrosion. Use only high quality
ethylene glycol antifreeze containing
corrosion protection inhibitors specifically
recommended for use in aluminum engines.
(SEE ANTIFREEZE CONTAINER LABEL).
Use only low-mineral drinking water or
distilled water as a part of the antifreeze
solution. Water that is high in mineral
content or salt may be harmful to the
aluminum engine.
Using coolant with silicate inhibitors may
cause premature wear of water pump seals
or blockage of radiator passages.
Using tap water may cause engine damage.

The info I got from the label is its 50% antifreeze 50% Water. Contains ethylene glycol, Recommended for use in aluminium engines.
The information I got from Halfords website states that it is Organic Acid Technology based.
Therefore it is incompatible with the PCX.
Using OAT based coolant may result in gooey gunk blocking and/or damaging the cooling system.
But hey, it's your engine, stick what you like in it

you you wrote:There's no doubt. If he is changing the fluid they are both fine
Key thing is to avoid silicates which neither of them have
You're correct about the silicates issue but wrong about both being OK.
If an OAT based coolant is to be used the entire cooling system must be thoroughly purged or a jelly like substance can form.
If you're happy with jelly in your cooling system, then carry on.
Best to replace like with like imo.

But its changing where the problem lies.
If the old coolant isn't properly purged from the system the jelly can form.
Why would anyone take on the hassle and risk when you can just use the proper fluid instead?

I'm with GN2 on this one -- coolant is too essential to mess up, especially with how infrequently it's changed.
The first link is silicate free -- which is good. Like GN2 said though, it's organic and can get gummed up. Honda's extended life coolant (the stuff OriginalRocket mentioned) doesn't have that.
The second link you should ABSOLUTELY WRONG because it's silicate-based. It'll destroy your coolant system.
Just get the Honda brand coolant, it's the safest way to ensure you're okay, and it'll last for YEARS...
