I want to remove a pipe plug on my Cummins 6BTA5.9 M3 370. It is adjacent to the thermostat housing and forward lifting lug....see photo attached. I THINK it is a 1/2" NPT plug; it has a square drive socket head (3/8"??...not sure).
It hasn't been touched for 17 years. I put a ratchet socket wrench with an extension piece onto it but the ratchet was going to break before the plug moved.
What are the 'trade secrets' for getting this thing out?
