Can a surfactant* ( in water in radiator ) noticeably cool engine, if water temprtre is just 70°C ?

*e.g. Purple Ice, Water Wetter.

As long as it doesn't foam and is not corrosive, at least it shouldn't hurt
anything.

The physics are as follows:
For optimum cooling, the system should be in turbulent flow in the radiator,
the
radiator should not be internally or externally fouled with anything, and
there should
be ample water and air flow.

( We've been through that crap about water circulating too quickly through
the radiator
to be cooled. Was always crap, is crap now, and will always be doofus
physics.)

The surfactant may be able to help cleaned fouled surfaces. It might even
cause an
change in the effective Reynolds number. Since it reduces surface tension,
it might
even allow water to pass a little faster through a radiator core.

And last of all, if it is of the correct type, it can actually give a little
lubrication to the
water pump. (Block polyols can do this if chosen carefully).

Try it and report back.

I run a waterless coolant in my bike. Stuff works great. We run a
surfactant in our Fire trucks, both in the cooling system and in the
tanks. Keeps the systems clean and seals last a LOT longer. We use Basic
H in the tanks and Water Wetter in the radiators.

Can hurt buyer's wallet ( Water Wetter is retailed here @M$48 = US
$12.63 ) & waste his time in draining out radiator etc.

I can try a cheaper brand ( TopOne, Coopel ) if they have no antifreeze.
Most brands ( e.g. Abro, Bardahl ) sold here have antifreeze ( useless
here ).

If a * can work in water 40-90ºC, then buildings' central heating
systems can use * too. Is any * used in US / Canada 's central heating ?

In the USA, our central heating systems are not usually hot water exchange
systems. They are often
either gas fired with heat exchangers or electrical heating. I have never
seen an instance where
such a product might work here.

Now, in cooling towers chemicals such as surfactants ARE used incorporating
antifoulant properties, antifoam,
etc but the application is not quite the same.

If you just remember that to have best heat exchange from a water (or
liquid) to air, the liquid should be in
turbulent flow inside the exchanger and the surfaces should be clean. If
neither of those issues is a problem,
you are probably wasting your time with chemicals.

Thanks for reply.

No waste ; I've found & put a cheap ( M$3.70 for ½ litre ) brand into
my Mitsubishi 4G15P engine's NipponDenso radiator, result is
fantastic : cylinder head is much cooler, even before water ( entering
cylinder head ) reaches 60°C.
