Jack,
I find that with straight water, and water wetter, -my car runs about 10
degrees or more cooler, than it does with anti-freeze. (Better heat transfer).
-This may not seem to be a lot, but in the summers here, it can be the
difference between smooth sailing, -and boiling over.
--Of course, here, pure water would freeze solid and damage the block, in the
wintertime, -so I put antifreeze back into it, before the first hard freeze in
the fall, before putting the car up for the winter.
I think a substantial number of owners over here who experience high heat in
the summer run straight water with a wetting agent. Probably no need to, in
the Netherlands, since it probably does not get as hot?
Never heard the idea that exchanging the coolant could contribute to
corrosion. -I've seen no evidence of rust, in the brief period since this
car's resurrection. Thanks for the heads up, though.

David,
I wish I could take mine out - but unfortunately the brake pipes are
still out, and so is the clutch pipe, and the engine and gearbox are
still on the garage floor, and the body parts are still with the
painter. In short: I'm afraid I'll miss this season. But the real reason
for my reaction is your comment about draining the antifreeze and
putting straight water/water wetter back in.
Over here it is a general rule to leave the cooling system as
undisturbed as possible: once you fill the system with an anti-freeze
liquid (or 'permanent coolant', as the expression is here), you just top
the system up and keep that fluid in the system all year round. The
thinking here is that emptying the system and filling with fresh water
brings a lot of fresh oxygen in the system which will cause corrosion -
the smaller the oxygen intake, the lesser corrosion you can expect.
Is your viewpoint (to change winter to summer and summer to winter) a
general opinion, or is it just your private point of view?
Looking forward to your reply.
Kind regards,
Jack Aeckerlin, The Netherlands
