Are the freeze plugs behind motor mount on a 1992 dodge 5.2 L?

No, freeze plugs (also called core plugs) on a 1992 Dodge 5.2L V8 are not typically located behind the motor mounts. They're usually found in various locations on the engine block itself, often in less accessible areas. While their exact positions vary slightly depending on the casting number of the specific block, they are generally on the sides and the back of the block, but not directly behind the motor mounts.
