My Toyota it's freeze plugs blow. I need to know how many there are and what to do

What is your question?

This just happened after I moved to Oklahoma from California. I think that the water froze in the car and the pressure blow the plugs . I didn't know that you were supposed to use antifreeze in the car out here in Oklahoma. Found one of the plugs and put it back in,but it still leaks from the engine.

What makes this problem better or worse?

It won't start

How long has your 2007 Toyota Highlander had this problem?
