<p style="margin: 0px;">While we're (sort of) on topic, what is the List wisdom on the efficacy of fitting side vents to the front wings (a la rally cars)? Since, supposedly, a big part of the issue with Healeys overheating is insufficient airflow through the engine bay, I'd expect them to help quite a bit. Or, or they 'useless' as well, since the main overheating issue is stopped at idle?</p>
<p style="margin: 0px;">Not sure if the louvers on my 100M help. It still gets a bit warm stopped at idle, but not as much as my BJ8 (but I haven't driven the M as much, smaller engine, etc.).</p>

<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>

<div class="gmail-_1mf gmail-_1mj" style="direction: ltr; font-family: inherit;"><span style="font-family: inherit;"><span style="font-family: inherit;">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.</span></span></div>
