You are right, Paul. Someone, Trico I think, sold a system that used coolant hoses to heat the washer fluid pipes.
I had one on my Renault 5 Gordini. It was a blue plastic heat exchanger about 5" long and about 3" in diameter. You cut a coolant pipe, slice about 5" out and re-fit the ends over the heat exchanger centre stubs. Then cut the screenwash tube and connect it to the smaller stubs.
Odd thing is, for such a Heath Robinson affair, it worked a treat if you gave the coolant time to warm up. It must have been a pretty efficient heat exchanger.
