[Healeys] Aluminum Radiators available

Wed Jul 19 21:41:28 MDT 2017

Hello

While aluminium radiators are very popular you should be aware that when you
compare the heat conductivity of the metal against copper it comes a very
poor second. Copper is are far more efficient at conducting heat than
aluminium.

So the fitting of an aluminium radiator to your car alone is unlikely to fix
the problem. It may look pretty under the bonnet but if that's all you do
the problem is unlikely to go away.

My guess is that there is sludge at the bottom of the radiator and in the
block. While the car may operate in the normal heat range during everyday
driving as soon as you extend it a little during hot weather it can't cope.
The more sludge there is, the less coolant there is and therefore the
ability of the radiator is decreased.

There are products out there that will eliminate that sludge.

Plus make sure that all the wind deflectors are fitted, water pump impeller
is not worm etc etc.

Kees:

I am not sure how I would check the water pump for cavitation. It is the
original pump as far as I know, but I bought it in 2001 with about 45000
miles.  Car has about 58000 miles on it now.  I have a correct sleeved
thermostat fitted.  I have thought about the electric fan, but I don't think
it would be a factor at highway speeds.  I have a higher efficiency fan
blade fitted.  The electric seems like ,it would be more for keeping it cool
at low speed driving or stopped.

I'll think about having a different core fitted to my radiator. That may be
a better way to go.

Thanks
