Review on Four Seasons 84802 Water Outlet by John Bennett

Incorrect product description. When I asked what it was cast from, customers replied. One said it was double steel, I don't know what "double" means. No response from the seller I do not believe. It is made of cast aluminum. I was hoping it was cast steel. I will use caustic soda to clean a cooling system that has a water outlet (thermostat housing) as its only component. I'm leaving this one out because the aluminum that's in there now will likely be destroyed and need to be replaced. Also asked for tapped holes. There are no threads in the holes, the holes are through because it is mounted on the cylinder head, there is a thread in the cylinder head. I believe that this seller is not conscientious.
