Groco FW 736 Heat Exchanger maintenance

While doing work on the cooling system on my Yanmar 3qm30, (new exhaust mixing elbow and manifold,) I thought I would do some maintenance on my heat exchanger. I wonder if anyone on this list has one of these, or knows where I might get instructions for disassembly.

Or should I just clean the outside, and put something caustic into the raw water side of the fins, and rinse it out?

I know it needs a few new gaskets, a new thermostat, and a brass plug on the end will need to be drilled out and replaced as it broke off.

Recommendations would be appreciated.

Radiator shop, if you can find one anymore.

Got it apart, a local machine shop drilled out and re-tapped the bad plug.
I am not sure what to soak it in, and i will probably need to make my own new gaskets.
It looks pretty good inside.
