96 civic ek9
Hello my civic stupidly sat for about 8 years without ever starting or moving. To my luck its still running great apon initial startup with fresh oil. Drove it a little runs good. Rad fluid was low and degraded.. fluid obviously needed more than the usual top up and rad is looking rough and rusted . Have a better identical rad to replace with better hoses so figured i would remove rad and instal different one with fresh fluid and would be a more effective way of flushing system. Removed upper rad hose the metal connection that the clamp goes on has a chunk of metal missing on it about the size of a small cotter pin. Sorry for the novel but will the chink of metal get into the engine ?
