Can you mix coolant?

[Gaz929]

Guys I've just put a blue coolant hose on my 14 450f and tried my hardest to catch it all to put back in, now my question is can I top it up with a different colour and brand of coolant? ? ?

I suggest putting in all new coolant

Many times during 100 mile rides or races I've mixed coolant. Beggers can't be choosers, and results were good, but if you're in a garage and have the time and doing a good maintenance session why not put in the same color/brand.

There are 3 basic types of coolant; ethylene glycol (typically green), propylene glycol, and oxalic acid ("Dex Cool").  You should just straight up never use Dex Cool for any reason.  EG and PG coolants will mix, but it's a whole lot better not to, especially when the whole system holds less than two quarts, and isn't any more difficult to drain and refill that it is.

I've drained and flushed all the factory stuff out and put new in which was pink in colour "Motul"

Cheers guys.
