[Healeys] Auxiliary electric fan

[Alan Seigrist]

Kees -

Living in hot and tropical climates like I have, I can confirm that using
cooler thermostats helps a great deal to reduce heat spikes in traffic, as
there is significantly less heat energy stored in the coolant at 165F vs
180F.  That combined with a well sorted system will be sufficient to give
you a few more minutes at idle than if you were running a 180 or 190F
thermostat on a very hot day.

You are correct it technically will not prevent overheating, but it will
postpone it long enough until you get driving again.

Best,

Alan
