Town and country 2010 3.8 - Hello, Is it recommended that I flush antifreeze and K-Seal out of my radiator and start over and put new coolant and K-Seal in for a second time for a blown head gasket?
Yes, you would want to do that and use clean coolant. But I'm not a fan of that case seal. I've had better luck with the bars, head gasket, sealer kit, the more expensive one that they sell in most auto parts stores like O'Reilly. I've had better luck with them but realize if that doesn't work you're going to have to tear the engine apart

Thanks for the reply Scotty!
Realize that kind of product is a temporary band-aid at best that at worst can leave you with a clogged cooling system. Assuming the stuff works at all (apparently you've already tried once and failed), if you're expecting to get years of additional service out of your engine that way you're most likely going to be disappointed.
@chucktobias I don't believe it failed, because it is holding temp it just every now and then goes above the mid way on the dashboard thermostat reading. Thanks for the reply.
Keep an eye on it and good luck.
