I was reading the bars leak instructions at Walmart and it stated you could add right in with the antifreeze, well I got the K&W instead and wasn't thinking about it and put a full bottle in my radiator to try to fix the leak, well I started the engine and it was running fine for a bit, then it all went downhill, started running very rough and stalled out, I later read the K&W instructions and it says it NOT compatible with antifreeze and severe engine damage may occur... Is there any hope for my 97' jeep 5.2L????
