What is a couple of cans of Bars Leaks?
What does that stuff do?
Where do I get it, and is it added to engine oil, gas tank, or cooling system.
Will this cure the symptoms or the problem?

Bars Leaks is a coolant stop-leak the you add to the cooling system. It will plug small coolant leaks though out the entire engine/cooling system. Bars Leaks is just a product name that I have used in the past with good sucess. Alumi-Seal is another good one. These stop-leak products are available at any auto parts stores (i.e. AutoZone, O'Rilleys, Advance Auto, NAPA, etc.). Just follow the directions on the can. Give it a shot, it just might work and save you some $$$$$ too.
