Removing coolant pipes from under manifold ?????? HOW

So I recently blew my 4.0 in my Tacoma (cylinder rod bearing(too much dirt in the engine(Nonstop off-roading))) decided to swap the engines myself instead of dishing out $1000-1700 to a shop. Anyway there's a coolant pipe that runs along the top of the heads and under the manifold that as far as I can tell is wedged in there real good. Before I started bending shit wanted to see if anyone has had this problem and has any tips

 

That tube is bolted to the engine block, don't try to just pull it out. I don't know if you can remove it with the heads on.

 

I've already taken out the bolts and I wouldn't have any problem with just undoing the head and taking it out but it's putting it back on my new engine that's the problem. As soon as I crack the seal it's bye bye warranty

 

Once the bolts are out the only thing holding it in is the O ring. Lube up with liquid wrench and it should pull out.

 

Have to have timing cover off I believe.
