There's discussion of finding the "proper" radiator once the incorrect one is out. Why not use the sawzall, or a hammer and chisel, or tin snips, or a smoke wrench (ok, maybe not a torch) and cut the offending unit to pieces, getting it the hell outta there? Get a long pry bar and smash the middle out of it. You'll have plenty of room, then. I mean, you're not gonna save it, are you? Why are we trying to salvage the existing monstrosity?
Or, am I missing something? (quite possible)

DO NOT go pounding away trying to break the water pump or clutch apart. If you crack or break the front timing cover you're F'ed. They're still available, but expensive. Not something you want to damage due to carelessness.

Get the fan/clutch and the radiator out however you have to without resorting to pounding on the engine. It's all junk and being replaced anyway. Damage as little as possible so you're not hunting down other parts that became "collateral damage"

It didnt just magically pop in there. There’s a certain way it was installed and it needs to uninstalled that same way. Shouldn’t need to pull the engine.. cut things. There has got to be a rational way to remove it

Can you remove the water pump with the fan and pulley still attached?

Trying again.

Worked that time. For some reason my original post didn't like this second image.

I was referring to the radiator. Not the water pump/pulley ass'y. Radiators are fairly fragile to begin with. Wouldn't take much to crunch up/cut up/dismember the rad (avoiding collateral damage, of course) and remove it.

what about cutting out the bottom support bar of the rad on each side and dropping it out the bottom and then rewelding the piece? that would be relativly simple, no?

The clutch has a protrusion on the rear of it that fits into a cup on the end of the water pump shaft. It has to come forward to clear the shaft, regardless if you break it off. Same with the water pump, you have to come forward far enough for the impeller to clear the housing.

About the only other solution is to take a Sawzall and cut the shaft where the clutch is attached. Take it out in pieces, get that stupid radiator out of there and find one that will fit better. There are many maintenance items on the OM603's that require the radiator and/or clutch fan to be removed for access. This will not be the last time you battle this issue. At least make it easy to remove the radiator.

Can the radiator be un clipped, then turned 90 degrees and then lifted out, or lifted a bit then turned 90 degrees?

I like that idea. If you're not the welder, I'd find one and have them look at the situation first though.

Can you fabricate a bracket that bolts into place after you cut the support? That way if you have to remove the radiator again, you will not have to cut and re weld again.

^ I like that.

That looks like fun. Ugh.

Maybe you can get in touch with the seller, who may know who did the conversion? They may be able to give you an idea of how to pull off that job without bloodshed, if possible.
