<div dir="ltr">On the '77 - '80 cars, the radiator was moved farther forward (I think to allow room for the V8 engine) so the mechanical fan would no longer have been any use. So they put the electric fan in (also, I assume because of all of the emissions stuff, especially the catalytic converter, underbonnet temps may have been higher). On my '76, when I need to reduce the level of coolant, I disconnect the lower radiator hose. It's messy but fairly quick and not too difficult. But yet, a lower petcock would have been nice.<div><br></div><div>Dan D</div><div>Central NJ USA<br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><a href="http://dandibiase.cbintouch.com/" target="_blank">http://dandibiase.cbintouch.com/</a></div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Feb 8, 2020 at 12:51 PM S.Carr via Mgs <<a href="mailto:mgs@autox.team.net">mgs@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 lang="EN-US"><div class="gmail-m_7969240240846205291WordSection1"><p class="MsoNormal"><span style="font-size:12pt;font-family:Arial,sans-serif">A friend who runs a small shop is working on a 1980 MGB—the first rubber-bumper B he’s encountered.
