Bar's Leaks Powder Radiator Stop Leak has millions of tiny particles to permanently seal leaks in plastic, aluminum and metal radiators, heater cores, blocks, heads, gaskets and freeze plugs. In addition, it inhibits the formation or rust and scale, neutralize pH imbalance, controls electrolysis, lubricates and seals internal, external and coolant-to-oil leaks. The Bar's Leaks Powder Radiator Stop Leak uses the same active ingredients as the liquid version but is available as a dry form in an easy-to-use tube.

on Bar's Leaks Powder Radiator Stop Leak
I am a Professional Mechanic. it should help depending on how bad the leak is. about the water pump, if it is just the gasket under the water pump this should help, how ever if it is the pump and not the gasket NO it will not fix it. if it is the pump then it really needs to be replaced asap unless you don't mind burning up the engine when you run out of anti- freeze or water when it over heats.

Will this product stop oil to water leak?
I' m seeing oil in radiator. Engine runs fine. Will this product fix? Also how do I clean radiator prior to adding stop leak? Are there any negiative effects on heater core or radiator? Is this a graphite product?
