I have thought about this a few times and forget to ask if this matters, . do we just not worry about that extra quart or so that is in the cooler and cooler lines, OR option 2 drain it or 3. run it after changing it, long enought to open the thermostat that allows for the oil to circulate thru the cooler and run it for a while and then change it again?
seems we are only getting about 3/4 of the oil out and changed if i leave it in there- my motor is a stock 2.0 and the cooler was installed at Tangerine racing, it is small one that comes off an adaptor plate on the oil filter location.

thanks for the input.

On a related note - how do you properly fill a system with a dry cooler? The thermostat will be closed on a front mounted cooler so how do you get oil into that part of the system so the level doesn’t drop when the thermostat actually opens?

I put some oil in the cooler before attaching the lines. My lines enter at the top so it was easy.

I don’t think anyone really worries about getting the old oil out of coolers on all the modem cars. Like superhawk said, it’s very little volume.
