So I went to drain the block tonight because its getting cold. So far I removed 2 plugs from the block (port and starboard side), exhaust manifold hoses, impeller hoses and T-stat to circulating pump on crank. Does that sound about right, or is there more plugs on the block to remove? Also how do you remove the T-stat? I removed the bolts and cover on the top of the block, and I see the T-stat but it doesn't seem to want to move.
