<div dir="ltr">Gary,<div><br></div><div>I had the same options when restoring my Mk1 BT7. I looked into aluminum radiators extensively to see what the benefits might be. Contrary to popular belief it is not better heat transfer properties of the materials. The copper radiator fins on the original Healey radiators have much better thermal conductivity than aluminum. The advantage of the aluminum radiator is the manufacturing process and the formability of modern aluminum. The result is more tube and fin area. I estimated a Wizard radiator has about 25% more fin area than the stock radiator. The greater the fin area the better to expel heat.</div><div><br></div><div>Having said that, there is a third option which is to replace the original core with a high efficiency core. This retains the stock look of the engine bay and will be close in performance to the aluminum radiator. The high efficiency core option will be more expensive than a Wizard radiator and the difficulty is finding a radiator shop that can access the core can do the work.</div><div><br></div><div>This website has a good overview: <a href="https://usradiator.com/cores">https://usradiator.com/cores</a></div><div><br></div><div>Harold</div><div><br></div><div><br></div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Jul 11, 2023 at 9:12 AM warthodson--- via Healeys <<a href="mailto:healeys@autox.team.net">healeys@autox.team.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div style="font-family:"Comic Sans MS",sans-serif;font-size:16px"><div></div>
<div dir="ltr">My 100 radiator is in need of some rehabilitation. It either needs to be boiled out, which would not replace some of the damaged fins, or re-cored. I am leaning toward re-coring but that would be more expensive, which leads to the aluminum option. </div><div dir="ltr">Besides price what are the pros vs. cons of these options?
