I started searching for Robershaw Thermostats this morning. I found this
page: http://www.stewartcomponents.com/tech_tips/Tech_Tips_3.htm From this
info, they are Stewart/Robertshaw now.
This PDF <http://www.stewartcomponents.com/catalogs/stewart_catalog.pdf> on
page 20 lists some, but I am not sure what size mine is without going out
and measuring.
Looks like they already have holes drilled in the modified ones for bleeding
and bypass. I have always put a 1/8" hole in mine.
Advice is appreciated.
Mine is at 220 on the gauge almost all the time. I think I have a 195 in
there, and would like to go to a to a 180 again. The only thought, is that
sometimes the engine will idle up again if the temp sensor doesn't see it
hot enough. I think that the idle was more consistent with the sensor in the
intake, instead of the thermostat housing, and I may move it back if I have
the system open again. We moved the sensor when we did the serpentine swap.

plug in the intake where it used to be.
Thanks!
