[Healeys] Texas cooler

[Michael Salter]

Alan is correct. The seal in the water pump is a carbon ring under spring
pressure against a cast iron surface. If the spring is too strong the seal
wears quickly so the design is such that there is sufficient pressure to
resist the design pressure of the system and little more.
Modern pumps use ceramic seals an can therefore withstand higher spring
pressures.

Michael,
What will give in the water pump?
