I have a 2009 Suzuki M90. I'd like to flush the cooling system this spring and replace the coolant with some fresh stuff. I've had the bike for about 3 years and I'm not sure if it was ever done before. The manual calls for a coolant that is compatible with a aluminum cooling system. The current coolant in the bike is green in color so I just assumed that it was standard engine coolant and would mix up a fresh batch of Prestone and be good. However, after having a look at the Prestone website they say nothing about their standard green coolant being compatible with aluminum systems. The orange Dex-Cool coolant does however state that it is compatible with vehicles with aluminum systems. Which of these two would be recommended in my M90?
I've also considered using a newer coolant product like Engine Ice but at almost 3L of coolant required even I can't justify the cost!
What does everyone else use and/or recommend?
