No cooling issues but...I bought one right after they were introduced and, while cleaning the block, found a lot of casting junk in the water jackets. It looked like lava rock and some of it had heavy pieces of wire embedded in it. I spent a lot of time with a hammer and a long screwdriver breaking up the chunks so they would fall out when I turned the block on the stand. Some of the pieces wouldn't come out so I installed a cooling filter in the upper hose. Time will tell.
