Here's the engine before I got started.

Oil cooler assembly removed. Just remove the 4 nuts on the thermostat housing and lift everything out.

Assembly on the vise. Not IN the vise! 4 nuts hold the cooler onto the thermostat housing.

New parts and gaskets. Now is the time to replace the fuel pump gaskets if they are leaking. Thermostat O-ring not shown.

Everything re-installed. No more leaks! Lucky for me the thermostat only goes in one way, I didn't pay attention when I removed the old one.
