Hi all,

I recently had new head gaskets installed in my grand am, but after
getting everything back together, there's still a leak into the coolant
line.  We came to the conclusion that there must be a crack in the head
somewhere.  In a final effort to keep this engine, I bought some "Seal
Up" from CarGo.  It will supposedly fix such a leak.  Has anyone used
this on a 3400 V6 or have any idea how I can get it into the coolant
line while it's running?

Thanks!
