Auto Parts: removing a starter, liquid wrench, impact driver

Question
I have a mustang 1990 2.3l I've been trying to remove the bolts off it to get it checked and possible replace it the bolts wont come undone with a ratchet or wrench I also used liquid wrench what should I do?

Answer
    Kind of strange that they should be stuck so firmly, but things like that happen all the time.  You are going to need an impact wrench or, if there's room to swing a hammer, an impact driver (all hardware stores have these).  The impacts will loosen the bolt without breaking it.
