Hi Larry,
Yes, it is the best to have the cap at the highs point, but it is not the
end of the world if it is not. It will be harder to get all the air out. You
may think about the vacuum system we talked about a few months ago. I never
used one.
There will never be any siphoning effect with the overflow tank. Water going
into the tank is then the system pressure exceeds the cap pressure. The
water in the overflow tank enters the cooling system when the system cools
down and creates a vacuum in the system, that then draws the water back in.

John,
I hadn't thought about the siphon effect.
With that in mind...
As long as the coolant level in the overflow tank was lower than the filled
surge tank level, there should be no siphoning effect, right?

Larry,
I agree with your thoughts on the surge tank. The cap needs to be at the
highest point on the system. You could probably lower the surge tank and
extend
the fill fitting and cap up to become the highest point in the cooling
system.
The overflow tank could be located above the fill cap, but when you removed
the
fill cap to check the coolant level, coolant would siphon/drain from the
overflow tank and create a mess unless there was a shut-off valve adjacent
to
the fill cap. The problem here is the old memory thing..........and we
all
know how that works.
