age they flex more. They have taken out several radiators over the years. I have no problem with a noisier fan designed to keep the heat down than use that cheap plastic fan. Like I said to each his own.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">The noise was excessive in my Austin-Healey (can't speak to Austin-Healys). The fan all but drowned-out the engine at idle and I didn't like sitting in a cloud of dust (but it was the most-effective temp-lowering
mod I've tried). Note the fan BCS originally sold was different than what I think they sell now; it had massively curved, rectangular blades--seven of them--that went from a couple inches of pitch to near-flat as speed increased. <br>
<br>
I only replace cores once (except when a water pump shaft broke and sent a fan into the radiator).<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">Except flex fans are extremely noisy. I got a 7-blade SS Hayden flex fan and BCS's own home-rolled shroud from them decades ago, and it was good for a 5-10deg reduction at idle but, damn was it loud (and it
would blow clouds of dust out from under the car when stationary). Ditched it for a TC (but kept the shroud). Some SS flex fans are known for throwing a blade. <br>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif">I inadvertently omitted an important detail: with the advent of cool weather in NH, rather than change the thermostat to 180 from 160, I slipped a piece of cardboard in front
of the radiator. I had driven 200 miles in back roads with the cardboard in place and the temp gauge never got above 170, and so I didn't watch the temp gauge while dashing down the interstate at 80 mph. I was unaware of any problem until arriving home, I
could smell radiator fluid. When I popped the hood all was wet, hot, and steaming. Perhaps at speeds 60mph and below the fan blades didn't flex enough but at 80 mph, they did and thus I inadvertently caused the damage to the radiator. I doesn't leak. Today,
having removed the suspect cardboard, I'll venture forth and watch the temp gauge keenly.......rich<o:p></o:p></span></p>

will swirl around to the front and pass through the radiator again and thus seriously deminish its cooling ability.<o:p></o:p></p>

towards the radiator. The extra cooling tubes may have reduced the clearance between the radiator and the fan. There isn't much clearance to begin with. The combination of the two may have been enough for the fan to hit the radiator.<o:p></o:p></span></p>

up a steep hill the colling system should keep up. What was the water temperature gauge saying?<o:p></o:p></span></p>
