Temp Sensor for Cold Start Valve on MC2 200Q

[l.leung at juno.com]

Hello List,

Looking for advice as to the location of
the temp sensor that activates the cold
start valve on an 89 200Q, MC2 engine. Is
it on the coolant flange neck, on the side
of the head or the rear of the head (although
I still can't seem to find one back there)?
