Low temp in winter? Ideas?

[neoneddy]

This is an MC9 if it matters, with the shutters closed my temp reached 190-195, they never seemed to open. I didn't want to push the limits of temp.

That thing bolted to the roof of the engine bay is not the shutter stat, it's the air filter, water trap and shut-off valve.  On my bus the shutter stat is bolted into the water pipe off the thermostat housing that goes up to the left (drivers side) radiator from the left hand cylinder head.  Excuse the picture, it was snowing when I took this 7 years ago almost to the day (7 years and two days, to be exact.  How time flies.)  The shutterstat is the small (1" diameter, 2" long) brass dealie with the silver top sticking out the side of the water pipe just above the exhaust pipe, to the left of the fan belt.  It has two air lines connected to it, one feed line from the aforementioned filter, and one output line that goes to all the damper and shutter air cylinders.  It should open at 170 degrees.  That one is brand new at the time, I got it from Luke.
