Ya, winter is upon us and I for one don't feel like freezing my butt off this year. My GSR through tons of heat back in '95 but she's not so warm anymore. I'm going for a 192 thermostat since I think the stock one is still in it (I think a 170). It has been suggested to me that I get a new rad cap too. I don't see how that can help but what the hell, they are only $10 or so.

But I want to change the antifreeze too and I've done this type of service many times, but I'm curious if there are any little tricks to flushing the system out really good. Thanks in advance.
