I'm changing the coolant on my 2009 Piaggio MP3 400 IE and I notice that the coolant is green and as far as I've read this takes pink coolant. I believe that the previous owner when doing maintenance put in the wrong coolant and I'd like to put in the right coolant but I've read that when they mix you could run into some issues.

Should I go ahead and put in the pink coolant or should I go buy some green?

Thinking also maybe several drain and fills with pink coolant should do that job as well.

The colour is completely irrelevant! Different manufacturers have the same basic coolant but with different colour additives.

Just go by the spec. when replacing or topping up. Peak Global is fine.

I totally disagree with jim's statement on coolant colors.

google coolant color

they are standard colors industry wide for specific applications.

What do you recommend, old?

There might be in the US - but not elsewhere for sure!

Monoethylene glycol-based antifreeze fluid, CUNA NC 956-16

per the user manual

LOL, oil from Switzerland. $25 for a quart of coolant is highway robbery.

I've been using VW G12 coolant without any issues, meets the spec and it is a fraction of the price.

You can get it from any VW/Audi dealer

You might say "those crazy russians", but what if I tell you that G11 antifreese can be of any color?

Next

Again, same goes for G12 with any quantity of pluses and not only Russian.

So the color means literally nothing. More: the color now is added just to sell it to you, to make you "sure" it can be added to the one you already have in your engine.

And yes, you should not mix G11 and G12, but G12++ can be added to both G11 and G12.

Thank you Jah!

do as you wish and good luck

not my words but just 1 example

What happens if you mix dex-cool with green antifreeze?
Dex-Cool and traditional anti-freeze don't mix well. When mixed, these two products will react forming a gel that can prevent your engine from cooling properly. It can even damage multiple components of your cooling system which then must be flushed or replaced which is expensive.

OK, no dex-cool mixing with normal antifreeze - we all got that message ages ago. Now dex-cool may have a particular colour - but they don't have a patent or copyright or monopoly on it!
