[Healeys] Electric Cooling Fan

[Michael Salter]

One item that has been overlooked here.
It is imperative that the baffles at the sides of the radiator are installed
correctly. If these are not positioned such that they will prevent hot
engine compartment air from entering the front of the radiator the engine
will run hot. 
I have installed a lower baffle and tight fitting side baffles on AHX12 and
have to use a thermostat or it runs way too cold.. around 130 F without a
thermostat!!

Jack -

Len's suggestion is basically right.  Start with a complete cleaning of your
cooling system first.  The easiest thing is to have your radiator taken to a
local shop to be rodded and cleaned.

Also try a 20% antifreeze + 80% distilled water + water wetter mix.  That
really works well, but coolant needs to be changed annually.

Also make sure you are using a 180 deg or 160 deg thermostat, not a 195.

Finally, jet hot coating the exhaust headers does wonders to keep
underbonnet temps much lower.

do these things first before going to a rad fan.  It can make a huge
difference.
