Yes- inevitable air in the engine heats up and expands very rapidly on
start-up. The 'pressure tank'- really a de-aerator or 'surge' tank- is supposed
to remove this air while providing extra water to take up the void left by
the air, so this tank should be mounted as high as possible. Another reason-
the pressure tank has a joint around the middle and that joint is supposed
to be above the clamp ring. Mounting the ring below the clamp can cause the
fairly heavy tank (when full) to drop through the clamp as far as the hoses
will allow, as the rubber liner in the clamp is usually deteriorated. The big
overflow tank is just a catch-can or container and can go anywhere handy.
Cheers- J DeRyke
