He send to radiator shop to do it. Before the flushed it, can see the tiny holes/fins inside the radiator is jammed with dirt or something. After the flushed it, they look cleared and clean.
So now you are worried the dirt from the block went into radiator. But your mechanic should have flushed it properly before full install.....lol
