Well my radiator spewed all this antifreeze out and it seems like it has no holes i was driving and all this smoke and antifreeze was on my bumper was wondering what i can do i have that stop leak but dont kno if it works that good need help what should i do

 

Do you know where the leak is comming from? I wouldn't ever put anything in my coolant lines. But who knows maybe that stuff works. It would be better for you to find the leak or crack. If it's in your radiator your fucked. If its te hoses it's easily fixable.

 

just buy a new radaitor
