I'm going to change the anti-freeze in my 05, with a 5.4l. I can only find one block drain plug. on the left side of the block. Does anybody know if their is a block drain plug on the right side of the engine block? Theirs a hex head bolt the is down on the side of the block, near the oil pan mounting surface, but I don't want to go pulling it out, not knowing what it goes to.

 

I'm interested also. Just flushed my V10 last week and could only find one block plug too.

 

I did a little googling and the other drain plug is under the starter, which is virtually un-accessable.
