Stupid me assumed my antifreeze was fine and then we had some 2-5 degree days here. Well, one of the driver side freeze plug works! The one over the motor mount popped out. AS far as I can tell the rest are fine. What's the best way to replace it short of pulling the motor as everyone says? Can I remove the motor mount and put one back in? Whats the best way to get to that mount if that's a way to go?
