2.8L 12V sensor error

["Bryan, Curtis" <bryanc@wdni.com>]

I am having problems with an engine temperature system sensor in my '93
90 csq.  The coolant warning light flashes, even at cold engine
temperatures with a full reservoir of coolant.  All indications are that
the cooling system is working perfectly - heat works, car maintants
operating temp, etc.  I know there are 2 sensors - one is mounted at the
bottom of the coolant reservoir (it checks the amount of coolant), but I
don't know where the other one is (it checks the engine temperature).
Does anyone know the location and have access to a service manual that
gives the electronic specs for the sensors (resistance, etc)?  Your help
would be very much appreciated.
