>With the engine off,
and near normal temp, the temperature in the block will rise , sometimes
quite rapidly, as the uncirulated coolant absorbs heat still in the
hotter metal block. As soon as the coolant begins to circulate again,
the gauge returns to normal within a few minutes. =
Both my cars (72 BGT and 74 Midget) will do this if shut off for a
short period, especially on a warm day<
Rick,
The temp rises so high that I can feel the heat when i pop the hood. =
That's what led me replace the manifold. Remember the "Cracked Exhaust
manifold " thread.
Despite putting in a brand new manifold, I'm still getting what i believe=
to be vapor lock. I'm still waiting on a heat shield (hint, hint Ted) to=
hopefully cure that problem. When the needle shot out of the hot range
into meltdown range i became quite concerned. I do have a temp heat shie=
ld
in place (more to collect the dripping fuel out of the Z-S than anything,=
before I rebuilt it) - apparently it is too thin to prevent heat transfer=
from exhaust manifold to the carb. I would like to possibily make my own=
but I don't want to mess with this car just yet as it is now my driver to=
work (my usual regular is Binky, of "Can't get over 3000rpm fame")
Ah well, the temp should be dropping quite substantially here in NC for t=
he
next couple of days so hopefully that will alleviate the heat problem.
Regards, Adrian
