Will this work with a bypassed heater core? Or is the heater needed

If you’re trying to stop a leak in Radiator it’s fine to have a bypass and not heater core.

I have o ring leaking when cold and stops leaking when warm. Will this help?

It may, but it's main purpose is to stop leaks coming from small punctures or cracks. I'd recommend looking for products that work specifically on the seals, rubber O-rings or gaskets, such as NO LEAK. Hope this helps!

Say in i have a hole in my pump under here i pure the anitfreeze at an it leak out a little can i use this to seal the hole or what can i use to seal

"Hole in pump" Don't think this will work on anything bigger than pinhole.

in which country was this manufactured?

This product was manufactured in the United States of America. Thank you for the question!
