Is it unusal for a freeze plug to just come out when the weather is cold. I live in Louisiana and its never cold here but last week we got down to 19 two days in a row. My mom has a ford and my sister has a ford and both of them ( I was surprised but they are fords) lost their freeze plugs. I mean they were just sitting on the ground one morning with a puddle of frozen water under them! I drive a Honda

This only happens when the ratio of antifreeze to water is too low and the coolant freezes. Reinstall plugs, completely drain cooling system, and refill with a 50/50 mixture of recommended antifreeze (likely Motorcraft Premium, Green) and distilled water.
