2009 Toyota Corolla - $1,900

2009 Toyota Corolla S, ~219,000 miles.
I bought this car in 2014 with ~65,000 miles on it.
It has been my everyday driver until recently.
It started overheating, and I took it to the shop and they believed it was likely a crack in the head gasket after testing the coolant.
They treated it with something called Blue Devil that they said if the crack was small the treatment could help seal it, and they changed the thermostat and changed the coolant.
They drove the car for a week after treating it and reported no issues.
I have driven it a few times without any issues; however, they did say it was not a permanent fix.
It could run fine for a day or 10 years, but that it would not be a permanent fix.
The heat and a/c work.
