Usually, people add stop leak to the radiator when there is a coolant leak somewhere. I was just saying that I hope something doesn't start leaking now that the stop leak was flushed out. I was also saying that I hoped if there is a leak, that it is not leaking from the heater core as those can be quite expensive due the length of time the job to replace them takes.What do u mean? Sry im a newbie at this stuff
Hoping for the best for you and your car!
