you know what they say about used car salesmen??
theres all kinds of things you can throw in your radiator to stop leaks. if it will fit someones done it. some of these quick fixes stop the leak but unfortunatly the block up heatercores, thermostats, radiators. i heard a story about and overheating car and the radiator was full of rice!! must've seemed like good idea at the time. i wonder what that glass stuff would do if it got into the oil?? i'm sorry to say it but theres so such thing as a quick fix.. just bandaids
