<div class="aolReplacedBody"><div dir="ltr"><div class="aolmail_gmail_default" style="font-size:small">I never heard that explanation before. But along those lines, my old Jetta had a large hole next to the radiator. There was a rubber flap over this hole, secure only at the top. I think that the idea was that at road speed it would open and provide extra airflow to help keep the engine compartment cooler. But stopped, the flap would close off the hole, preventing hot air recirculation.</div><div class="aolmail_gmail_default" style="font-size:small"><br></div><div class="aolmail_gmail_default" style="font-size:small">Stu</div><div class="aolmail_gmail_default" style="font-size:small"><br></div></div><div class="aolmail_gmail_extra"><br><div class="aolmail_gmail_quote">On Fri, May 4, 2018 at 11:38 AM, John Watertor via Tigers <span dir="ltr"><<a href="mailto:tigers@autox.team.net" target="_blank" rel="noopener noreferrer">tigers@autox.team.net</a>></span> wrote:<br><blockquote class="aolmail_gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span style="color: black; font-family: arial; font-size: small;" size="2" data-mce-style="color: black; font-family: arial; font-size: small;" color="black" face="arial">There was a Tiger question years ago when someone ask this question in one of the sports car magazines, on why there was holes on the right and left side of the radiator mount sheet metal.
<div>The answer was, the holes are to let air flow over each exhaust manifold when driving to cool the under hood temperature. Did anyone else ever heard of this answer?<br>
