I replaced my water pump, and much to my dismay found another leak somewhere behind and below the pump. I was afraid that the head gasket might be leaking, and used Bar's liquid copper to try and abate the leak. I also removed the thermostat so that this product did not clog it up. This stuff worked great! I have put many miles on the truck without incident....I would recommend using this product should you not want to invest in having head gaskets replaced.
Recommends this product? Yes
