The radiator in my stang has 3 tiny holes in it. It dosnt leak untill i cut the car off. Then it spits out like pee lol. Will JB WELD FIX IT?

No, but WATERWELD will fix it. It's White 2 part solid clay type epoxy that will do the job for a little while.

Soldering is the only way to go because the expansion and contraction rate for lead solder is the same as the copper tubes. The waterweld and or JB will eventually come off.

Have the radiator repaired correctly.

X-2... That said a GOOD radiator shop can fix it for minimal cost, and then your not worrying when your home-brew 'fix' is gonna let go...
