RE: [ihc] T-stat basket case

Jim,

The moving "cup" part of the tstat goes down.  The "cup" has some holes in
it if I remember.  Another thing to note is to put the little cylinder
holding the wax pellet down, it has to be on the engine side, not the
radiator side.

Put it in a pot of water and boil it for a few minutes and you will see it
move.  It does take some time for it to react

Does the 'basket' of a thermostat go down (toward the block) or up (to
the heavens)?  Which direction should the plate move towards, as it opens?

Jim, with no model to work from.

Jim - Assuming we're talking about an IH SV-8....

Define 'basket'. If you're referring to the stamped legs that form a
'teepee', that goes up(pointing toward the water neck). No proper(read
RobertShaw) IH thermostat has a 'plate', rather it's a 'cup'. *Don't*
install a Stant or other brand, they don't block the bypass when open. Look
down into the t-stat housing block....see that cast-in feature in the middle
with the machined counterbore? That's what needs to be closed off when the
t-stat is open. The cup on a RobertShaw moves downward into the counterbore.
Toss one in a pan of boiling water and you'll see how it works. It's always
a good idea to check a new t-stat anyway to make sure it's opening at the
right temp(grab the candy thermometer).
