4kq dead temp gauge...

[Joshua Van Tol]

Or you could short the sensor wire to the block, which should cause the
gauge to show full hot. Or test it with a DMM. Simply measure the
resistance of the sensor, it should probably be in the range of 200
ohms to 10 k ohms. Don't know exactly what the spec is on those, but
most NTC type temperature sensors on imported cars fall in that range
at normal temperatures.
