If the leak is not to serious it will.<br>
But do not forget to flush the system truly and properly asap
when permanent repairs have been carried out.<br>

<p class="MsoNormal">Hi, </p>
<p class="MsoNormal">I’m losing a little coolant – say 1 pint
per 200 miles – from a pair of core plugs. (The two rear ones
under the manifolds).</p>
<p class="MsoNormal">No way to access them from above and I very
much doubt if it can be done from below though I haven’t
looked. I’ve got Webers and a big bore 6 branch so there’s not
much room.</p>
<p class="MsoNormal">OK, I’ll have to strip out the Webers and
drop the exhaust; that’s a given. And, at the same time, I can
do a few other little things.</p>
<p class="MsoNormal">BUT, but....I don’t want to do it now. Not
just when what we optimistically call our summer is just
beginning.</p>
<p class="MsoNormal">I hope to keep an eye on the loss and last
it out until autumn. (Usually summer starts in June and autumn
starts about a week later so I may not have much time).</p>
<p class="MsoNormal">I was thinking of putting some Radweld or
similar magic goo into the coolant. I know it’s fairly
effective in radiators.....might it work on the core plugs?</p>
<p class="MsoNormal">Simon</p>
