We only see temps around -10 to 15 at the most around here.. Do it however you want just don't wait to late.
I've done the same for decades and never had a problem. Doesn't mean draining it isn't a better method,
but if you put antifreeze through the system, what is there to worry about. yes you do need to warm it first on water, then switch. Local marina here does the same and I'm sure they aren't cracking blocks every year. We get very cold temps here.
Ayuh,... If the T-stat just happens to close when the cooler antifreeze hits it,...
Ask me that question again....
There are Hundreds of posters here every spring that think like yerself, with Cracked blocks...
You guys that are dumpin' antifreeze, are buyin' what 4, 5 gallons,..??
That's $20. $30. bucks or more Thrown away...
Drainin' it is Free,...
I boat til ice-up, 'n do it several times a year, for Free...
