the XU engines use a takeoff from the top hose and return into the bottom of the rad/expansion tank.
I would get some cooling system flush and run it to temp them dump it and run a hose through it with the thermostat out, a cheap way to do it is a dishwashing tablet/powder as its a degreaser.
its a heat exchanger, so yes it does cool, just not in the way the air-oil heat exchanger (cooler) does it, if your rad and cooling system has enough capacity you can run just the oil-water unit, which is common on race cars where packaging for extra oil coolers is tight.
