THe plug I am talking about is the one that if it where on the driver's side it would be for the coolant temp sensor. My plug is leaking coolant for some reason and I wanted to tighten it up to see it that would stop the leak.

I have tried all three size socket wrenches and they dont fit in there. I have a set of stock heads that still has the plug on it, and I tried it on it too. None of the socket wrenches fit it like the one on the front of the head

So what do you use to tighten that up with?

Thanks for any help

i have only seen one and it was in a techs box at the dealership i worked at

try this if you have a grinder

take a bolt and grind it square, i did that before i found out there was a pice made for it

If you could find a piece of 5/16" square stock that was sturdy enough, that might work. I think a few people have used that.
