<p>Hi Josef,</p>
<p><br>
</p>
<p>I agree fully with you that the running gear should be kept in
perfect condition to avoid problems. Not always the case in the US
where maintenance has a different meaning than in Europe. Cooling
problems can arise from a lean mixture or wrong ignition timing to
silted up engines and radiators due to lack of use of proper
coolant. I have seen horribly silted up engines and radiators from
the US and UK incl. in my own Californian car.<br>
</p>
<p>If I am correct the thermostat opening temperature on the A-H´s
is either 72°C or 76°C (US spec) which is more or less average.
You could easily go up to 86°C with a 10psi radiator cap and
proper hoses, preferably reinforced PU. A good high efficiency
radiator core should not hinder coolant flow and it even would
offer less resistance to flow. However there will generally be a
slight increase in airflow resistance. Some inferior designs may
hinder the airflow through the core considerably. Go to a proper
radiator expert restorer and do not always trust the guy around
the corner offering a cheap service. He may be an expert in
soldering but does not always understand the workings of a cooling
system.</p>
<p>I am afraid I am in no position in the Netherlands to avoid heavy
traffic, even in relaxed classic car events, so I stick with an
improved radiator core, 86°C opening thermostat and a properly set
up thermostatically controlled fan (98°C in, 92°C out), fixed fan
removed. Only let me down once when the fuse blew in the middle of
a hold up during an event. <br>
</p>
<p>I also use my car a fair bit except when there is salt on the
roads.<br>

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 no crude in the
water channels of the engine or radiator. Some high effeciancy
core radiators are also counterproductive, as they hinder the
flush of the water through the radiator.</span></p>

experiance of 40 years with Austin-Healeys and others like MG

Personally I avoid motorways with high traffic and always
congestions and driving through big cities like Cologne,
Munich, Stuttgart, Amsterdam, etc. from traffic light to

<p style="margin: 0px;">Yes and no.</p>
<p style="margin: 0px;">An old car should be fit for any normal
drive, be it regularly or occasionally, at leisure or in
modern heavy traffic. This means that many classic cars will
need some assistance with the cooling, i.e. an electric fan,
either manually or thermostatically controlled.</p>
<p style="margin: 0px;">An aluminium radiator is indeed a
gimmick and does not add anything at all. It will probably
wear out faster due to corrosion. It is just cheap to
manufacture and does not improve the cooling efficiency. </p>
<p style="margin: 0px;">What improves cooling efficiency is
increasing the running temperature of the engine by fitting a
hotter thermostat thus creating a larger delta T, fitting a
more efficient water pump to increase the coolant flow,
enlarging the total surface area of the radiator, i.e. more
rows (up to a point), larger matrix or increase the air flow
through the radiator, i.e. improved cowling, more blades to
the fixed fan, higher engine idling speed but most of all a
thermostatically controlled fan in combination with a
carefully chosen thermostat and thermoswitch.</p>
