I'm changing the coolant on my #2 2007 Anniversary VFR which bought used, so I don't have any maintenance history other than, "I always took it to the dealer". I drained the coolant and it is dark green, not the traditional fluorescent chartreuse I was expecting. I guess the dealer put it in, but I thought the Honda stuff was blue. Would this be something the dealer put in later, or did it come new with this dark green type?
At any rate, I'm thinking Zerex Asian Blue might be the way to go with maybe a gallon of distilled cycled through it a few minutes before draining and putting in the Zerex. I'm not really up on coolant technology, but I'm thinking with it being a 2007 and based on the manual, it came with silicate and borate free IAT and this dark stuff is probably dealer changed OAT.
BTW, is there any difference between the Zerex Asian Green and Blue colored stuff other than the names of the cars they stick on the front label and the order of vehicles on the back? Everything else on the label seems identical. Since it's a red white and blue bike, it needs blue coolant instead of green. 😁
Edit:
Some guys way smarter than me on Facebook tell me I'm good to go on Zerex Asian Blue after a good flushing.
