Is it OK to add anti-freeze to coolant?

To add anti-freeze to the coolant tank to make sure it doesn't freeze and crack?

U know what color antifreeze? Don’t wanna mix wrong color /type

It should already have some in it. It's just the reservoir for whatever is in the engine. It's not going to freeze.

I see no reason why not. If you don't have an antifreeze tester, I wouldn't add much, perhaps 1/8 cup at most. I believe you got the Ryker new this year; if so, it has a 50/50 mix in it which is good down to minus 34 (I think).

A tester is only a few bucks. Pick one up and check the coolant. Too much anti-freeze is not necessarily better. It will keep
it from freezing to a lower temperature, but may not cool as well when riding weather is back. Check it and don't guess, you'll
sleep better.

Unless you have put straight water in your system witch most people would not do these days, you have nothing to worry about it's not going to freeze!

Unless you have changed something. Or, the coolant is old. I don't see any reason to add anything to your reservoir. If you overfill it, you're going to have problems when the coolant comes to operating temperature and overflows the reservoir. If your coolant is good, there's no reason to mess with it. If it isn't, you need to drain, flush and replace it. If you replace it, you can use pretty much any product you want as long as it is silica free and aluminum friendly (which is the same thing).

The only other possibility is that you may be confusing anti-freeze and coolant as 2 different products. Actually, they are 2 different names given for the same product. Coolant and anti-freeze are one in the same.

Great, I guess that's one less thing to worry about. Thanks for the comments.
