FWIW........my recomendendation , and Bars Leak is the only leak-stopping
additive I use.......
throw it in the pressure bottle with a cold engine, then drive  for 20
minutes until warmed up.  That's it.

  I don't think it gets into the heater circuits too much myself.

Heck......there are vans where I WANT it to get to the heater
circuit......and it won't go there much at all.
Not unless I undo a heater circuit hose.
