Kees,
The running temperature of an Austin-Healey 100, 100/6 and 3000 engine is=

already relatively high. There is no need to increase it. But you need to=

have engine and radiator in as good as closely to new condition. That means=
=20
no crude in the water channels of the engine or radiator. Some high=20
effeciancy core radiators are also counterproductive, as they hinder the=20
flush of the water through the radiator.
My experiance of 40 years with Austin-Healeys and others like MG As,=20
Triumph TR2-3as, etc. are to kkeep everything to factory spec and the car=

runs absolutely fine in normal traffic. Personally I avoid motorways with=

high traffic and always congestions and driving through big cities like=20
Cologne, Munich, Stuttgart, Amsterdam, etc. from traffic light to traffic=

light. But those big cities I even avoid to go in with my modern car as its=
=20
a nightmare meanwhile.
I better use public transport for going in when I need to go.

When you use genuine parts to replace faulty ones and when you keep the
car propperly maintained and when you use the old car only
occasionally for fun drives just to enjoy driving it, there is no
problem with an old car.
PS: Aluminium radiator is something nobody needs in a classic car as it
improves nothing. Just a useless gimmick.

Aluminum radiator swap update:
Got my old oem unit out. Removed my nice newish metal flex fan. spliced
wires onto the electric fan for easy connect/disconnect and then went
to double-check the new radiator will work after and initial trial fit.
What I found: OEM radiator is 1/2" wider and the aluminum radiator does
not have tapped holes, so nuts will be needed to attach to my car. I am
outside of the return window.
So it looks like I will be getting my OEM Radiator flow tested and
tanked.
Will reinstall my flex fan
refill with coolant/water
have installed a new sleeved thermostat to replace the non-sleeved
unit.
I can make some shims for the new radiator, but cutting threads in the
holes will most likely result in the holes being to big for the bolts.
Fun with old cars
