I finally got around to changing out coolant. My scooter is over 10 years old and I don't think the anti-freeze has ever been changed. Manual says takes 1165cc of coolant which equal approx 39.4 oz. I drained out approx 26 oz by disconnecting the hose at the pump, per the manual instructions. The anti-freeze that came out looked OK, but a little heavy/ thick. I put back in approx 39.5 oz and idled it awhile and looked for any problems/ leaks. Level in overflow tank didn't change, so I took it for a ride and everything seemed to be fine.
I did some research on anti-freeze and didn't really find anything definitive on what to use. I went to the store planning to get dex-cool, but ended up buying generic WalMart SuperTech 50/50. I had to use some reading glasses, but was able to read the label on the dex-cool and generic products at the store and the WalMart brand read the same as the more expensive name brand. So, I got the cheap stuff.
The owner's manual maintenance schedule says to change anti-freeze at least once a year. After awhile I will probably flush this stuff out and replace again. Like anything else, anti-freeze breaks down and needs to be replaced. As I understand it, seals will last longer with fresh anti-freeze.
The engine seems to run pretty cool, but I seem to be running it harder and harder. Now, I am starting to run it leaner, I expect it to run hotter, so I want to make sure the cooling system is working properly. Cheers
