I know that this may be a dumb question, but how many freeze plugs are there in a 351w engine? The reason I ask is that one is leaking behind my motor mount on the passenger side and if one is bad I might as well change them all. With my body lift, it looks like I might be able to fix them without pulling the engine. It's been a while since i've had a Ford engine on a stand or replaced anything like freeze plugs. Also, are there any in the heads? How many are behind the flywheel (if any)? Thanks in advance.

 

There should be 3 on each side of the block , one in front & back of each head , 1 behinde the fly wheel , if i remember right ,and there really not freeze plugs , they have nothing to do with the motor freezing , there core plugs ...Lew

 

Thanks Lew! Yeah I know that there casting plugs but I was going by the more common term that everyone calls them. I don't really have any fear of my engine freezing in Florida but just wanted to change a rusted leaky one without pulling the engine. lol Seeing that they have one on the back of the cylinder head, it might be worth it to pull it anyways. It might be a good time to give the engine a good cleaning anyways while it's out too.

 

Yeah there not easy to get to , you need to pull the heads to do it right , i live in west palm beach so yeah we don't have to worry about freezing....Lew
