I agree with MOS.... Warm it up and get under there with a mirror and flashlight. Don't add anymore "mechanic in a bottle". That stuff only reaks more havoc down the road.
Yes. Stopleak plugged the radiator in my dad'* older truck

You are absolutely correct. It only leaks when the coolant is very hot (I'm not talking operating temp hot where the Tstat is open and the upper rad hose is hot, but after driving for a little while).

John Deere Boy, how long does it take the Super Leak sealer to work in? I've city driven about 15 minutes twice a day for the last two days. I also ran it for 20 minutes while parked as the instructions said.

I won't put any more in now.

Thanks, fellas.
