Now that we can hit the road again with our classics, it is handy to squeeze some strokes under the hood. The rubber can have aged over time.
And a coolant hose that looks pretty nice at first also when stored together, can have as many cracks and cracks as a Rembrandt or Vermeer. Pay particular attention to the places where the hose, or as it is actually called 'the shaped part', has bends or bends. The misery is often in the 'armpit' of the snake.
That doesn't have to be a serious problem, but it can be.
Replacement is a nice job. And can just care about a head gasket.
