I am trying to remove the oil cooler to gain access to the transmission cooler.

The problem I am having is the hose that is connected to the oil cooler has a bolt that is used to hold the hose to the oil cooler and it is frozen. I have been hitting it with penetrating lube all day but still will not budge. If I can disconnect the oil cooler hose where it attaches to the bottom of the engine, but need a good way to plug the hole. Any ideas?

Thanks

Subaru oil pan drain plug and copper crush washer that matches the port. I believe it's M18 but it may have been M20. You can find them at Advance Auto or O'Reilys.

I blocked off both ports and ditched the cooler when it sprung a leak on me.
