I don't think it's a trivial nor obvious task to remove the thermostat and plug the correct hole(s).
I spent several minutes looking at it and could not figure it out. Maybe if someone have cut the end tank in half and have pictures...
Even then I suspect you my not be able to get to the correct hole(s) to plug them.
Test the thermostat in hot water and put it back in the oil cooler.

I've been trying to solve an oil cooling issue for the last 2 weeks.
Everything I do seems to make it worse:
1. I built a flow guide on the prop side of cowling (pusher) to prevent
back-flow into cowl. Temperatures worse - removed.
2. I cut a new hole and fabricated a new exit scoop on the bottom of the
cowl to add 20" of exit area- Temperatures the same to maybe even worse.
3. I created a new oil cooling intake scoop that is 3 times as large as the
original bring the total oil intake area to about 20sq in. - no change -
maybe even worse.
So, I know I have plenty of exit and plenty of intake - what gives? AHA,
must be a flow problem into the oil cooler. I removed the thermostat - just
sure that it would get better. Took a quick trip around the pattern today
and it is definitely - WORSE. How can this be? Got down after my quick
trip around the pattern and put my hand on the end of the oil cooler
farthest from the inlet and outlets - cool to the touch - not even warm!!
How can that be? The oil temperature is still reading 180 degrees after it's
been shut down for 5 minutes!
Anyone have any ideas on how the check and clear a potentially clogged $575
oil cooler? Joe Hull
