I know there was a recent post about how to winterize the radiator but I can't seem to find it. I know I can drain the water completely or have a 50-50 mixture. What kind of antifreeze should I be creating the 50-50 mixture with?
Green, ethylene glycol.
How much "water" is left in the engine when you drain via the petcock? Is there still enough left in the engine to do damage during a hard freeze? I think there is.
Draining the water just promotes rust! You do not have to use a 50/50 mix. Look at the chart on the package for the lowest temp. in your area and mix to that level. I use the green.
Thank you Steve, that is the exact article I was looking for.
