Hi Fred,
I was surprised to see what your age is the other day. You olefart, you're
a year younger than me.
Schaller said that the bypass hose was to provide a faster warmup in the
chilly English climes. It kept some of the coolant from going into the
radiator. And of course, it's to use with the skirted thermostats which we
can't get anymore. My impression is that we don't need it, and the head
still gets adequate circulation.
