ECT sensor
Over the weekend the thermostat in my 1994 Vette went south taking with it the ECT sensor. During the event, the upper radiator hose was blown off of its radiator connection causing coolant to gush out all over where it shouldn't be. In the course of this mess, the Check Guages light came on and the analog water temp gage ceased to function; the Low Coolant light also illuminated. The digital water temp gage continued to work. My query is about the water temp gages.Do the digital and analog water temp gages receive the same inputs from the ECT sensor? Why would the analog gage fail while the digital gage continue to function?
Currently the only cooling system malfunction my car has is a failed analog water temp gage. Otherwise, this system has all new hoses and clamps (not the GM crap), new water pump, new thermostat and new radiator.

Have you tried to install a new senser to replace the to the temp gauge? Perhaps it is sending a bad signal or low signal to the gauge!
Thanks,Matt

On an LT-1, the analog guage takes its reading from the sensor in the water pump housing. The digital guage gets its reading from a sensor in the RH cylinder head.

Thanks for the info. Now I know what to do. Fix it when I can.
