I need to find out where the freeze plugs are located, and how many there are on my car? And how I can replace them without taking the engine out?
Do you
have the same problem?

Why are you replacing them? Are they leaking? If they are not leaking do not bother.

As to how many.
Two on each side tucked up behind the engine mount area behind the exhaust manifolds. One on each side in the front behind the accessory drive.
Two in the rear of the block inside the bell housing.
Out of all of them, there is only one that you can actually get to when the engine is installed.
