Oil cooler takeoff, wrenches needed

[Brad S.]

My cooler hasnt gone bad yet but I saw one on a pickup at a local salvage yard.
The fenders are off, the heads are off, pretty easy to get at the cooler. I thought it might not be a bad spare to grab and have it rebuilt before I really need it. Little cheaper if I pull it myself.
Wondering what wrenchs I might need to "pull" this off.

Aw I see what you did there. He is correct anyhow just splitting hairs a little.

You will not be able to just unbolt it from the block and pull it off. The motor mount is in the way below it and the exhaust manifold is in the way above it. So if you can remove the exhaust manifold it will just come up and out as one piece. Otherwise you will need to remove the bundle and rear header as one piece. Then remove the front header as itself. The front bolts are 9/16 hex and the rears are 1/2 inch hex. 4 in the front and 4 in the rear...

He said it had no heads gary, it will come right out...

Thanks guys, dieselcrawler that was hi larious, before I paged down I was already doing the math.
I don't know how long this engine has had the heads off, but the chance of water being inside the pan or block is pretty high.
Does water sitting inside the cooler pose a problem to the tubes?? I know freezing water would make it useless, and I suppose if I pull it and water runs out, thats bad.
