Description Two pin A/C coolant temp sensor (switch) for the 1G and GVR4 cars. Located in the thermostat housing. This is the “0ver-heat” switch that kills the A/C compressor in the case of over heating conditions. These should not be confused with the ECU Temp Switch (two made spade connectors @ 90 angles). These OEM units are in very limited supply at this point.
